The holiday season is a time for joy, celebration, and coming together, and there’s no better way to encapsulate this spirit than with a holiday party brimming with excitement and laughter. Recently, Paul Michaels Events had the pleasure of hosting an unforgettable corporate event for @properties. Big Mini Putt Club’s Lakeview location provided the perfect backdrop for this midday holiday gathering. This wasn’t just any ordinary corporate event; it was an experience.

A key highlight of the afternoon was undoubtedly our karaoke setup. While not every attendee was ready to embrace the mic, the many brave souls who did brought fantastic entertainment to the crowd. It was truly heartwarming to see colleagues cheer each other on and share moments of musical fun and camaraderie. Karaoke offers a unique avenue for employees to connect beyond the confines of day-to-day business activities, allowing personalities to shine in a relaxed and enjoyable atmosphere.

In the spirit of holiday cheer, @properties’ creativity shone through with a surprise visit from none other than the Grinch. This unexpected twist added an extra layer of fun to the event, providing attendees with photo opportunities and lots of laughter. It’s moments like these that elevate a festive gathering into a memorable celebration, creating a shared experience that participants will talk about long after the decorations have been taken down.

Our collaboration with @properties didn’t just result in a successful event; it solidified a relationship founded on mutual respect, creativity, and a shared goal of hosting remarkable celebrations. Paul Michaels Events was honored to be part of this celebration and looks forward to helping craft more unforgettable moments with @properties in the future!

As the holiday season sweeps through the Windy City, there’s one company that knows how to usher in the festive spirit with style: @properties! This year, they orchestrated a holiday party at the renowned Untitled Supper Club, transforming it into a vibrant epicenter of joy and celebration.

With around 400 enthusiastic guests filling every room, the air was charged with excitement and anticipation. Our team set up in one wing, equipped with an engaging karaoke setup, delicious bites, and a fully stocked bar. The guests, initially mingling and savoring the culinary delights, gradually turned their attention to the karaoke stage. Before long, requests started pouring in, and our room quickly became a hive of musical enthusiasm. Guests took turns singing beloved Christmas classics and popular covers, their voices resonating with joy and spirit.

While the @properties team knows how to foster a festive atmosphere, the guests themselves brought a flair and talent that could rival any professional stage. So many attendees showcased their vocal talents, making the karaoke segment a highlight of the evening. As the night progressed, the irresistible lure of the music and shared merriment meant that we went slightly over our set time. However, the enthusiastic response from the attendees was well worth it, as it became evident that our presence had become a cherished part of their celebration. The popularity of our karaoke setup underscored the magic of music in bringing people together, and our commitment to delivering an exceptional experience was fully realized.

As we reflect on this joyous celebration, our hearts are full, knowing we played a part in creating beautiful holiday memories. Thank you to @properties for trusting us with all of your festivities!

When it comes to hosting events, few venues can match the grandeur of the Chicago History Museum. This iconic location set the stage for Joe and Michele’s wedding reception, a night of enchanting music and lively celebration, expertly curated by Paul Michaels Events.

Uplighting adorned the venue, casting a magical glow over the entire room and highlighting the elegance of the historic space. The two powerhouse subwoofers, carefully set up by our team, ensured that the music would be as vibrant and compelling as the love story being celebrated. This perfect synergy of light and sound created an ambiance that was both sophisticated and inviting.

The energy at Joe and Michele’s reception was palpable from the moment guests stepped off the party bus. This vivacious mood carried through grand entrances, setting a thrilling tone for the rest of the evening. As guests settled in for a delectable dinner, they were treated a live performance by John, the groom’s brother and best man.

After a touching performance, the spotlight turned to Joe and Michele. Their first dance, set to Zac Brown Band’s “Loving You Easy,” was a tender moment that encapsulated the joy and devotion shared between them. As they gracefully danced, it wasn’t long before guests were inspired to join in, filling the floor with laughter, love, and plenty of moves. DJ Evan expertly guided the musical journey of the evening. With an innate ability to read the crowd, DJ Evan kept energies high and feet moving.

Naz & John’s Blooming Wedding at Garfield Park Conservatory in East Garfield Park, Chicago

There’s something undeniably enchanting about a wedding that blends the elements of a destination celebration with the vibrant energy of a city like Chicago. We at Paul Michaels Events recently had the honor of being part of just such an event, as we celebrated the love of Naz and John. Despite being from the East Coast, this couple chose the Windy City to tie the knot, inviting their family and friends to share in a weekend filled with laughter, memories, and unforgettable moments.

It’s easy to understand why the couple chose the Garfield Park Conservatory to host their celebration. One look around at the lush greenery that fills the venue and just about anyone would fall in love! The ceremony took place in the Palm House, located just beyond entryway of the conservatory. While we won’t be sharing photos of this portion of the evening due to the couple’s request for an unplugged ceremony, one can picture the beauty of this moment. Surrounded by cascading palms and the natural artistry of the venue, Naz and John exchanged vows in an intimate setting that highlighted the personal nature of their union.

Following the ceremony, guests transitioned to the Show House for a delightful cocktail hour. As guests mingled and shared in the joy of the newlyweds, all the wedding vendors, including our team from Paul Michaels Events, diligently prepared the stunning Horticulture Hall for the upcoming reception.

The reception itself was nothing short of spectacular. Given that Naz and John met on the dance floor, it was no surprise that their wedding reception turned into a lively, dance-filled celebration. The couple kicked off the festivities with a jaw-dropping choreographed entrance followed by their romantic first dance to “Kiss Me” by Sixpence None The Richer. The evening continued on with planned dance performances, injecting the night with a joyful energy and diverse cultural flair. One of the standout performances was a Bollywood dance arranged by Naz’s college friends, which proved to be a testament to the couple’s shared love for dancing and cultural richness.

As the night unfolded, DJ Evan kept the dance floor packed, skillfully navigating the night’s playlist to keep spirits high and guests moving, even as a Chicago snowstorm started outside. The celebration unfolded seamlessly from the first dance to the last song, thanks to our commitment to creating unforgettable experiences.

We at Paul Michaels Events would like to extend our heartfelt gratitude to Naz, John, and their families and friends. It’s always a profound honor to be chosen to celebrate such intimate, life-changing moments. Chicago welcomed this East Coast duo with open arms, and we are overjoyed to have been part of their remarkable day!

At Paul Michaels Events, we believe that every milestone—professional or personal—deserves the highest level of care, curated entertainment and flawless execution. Recently, we were honored to provide entertainment for the 2025 Physician Appreciation Dinner hosted by Rush Copley Medical Center at Hotel Arista in Naperville, Illinois.

Elegant Atmosphere, Expert Entertainment

The evening started with welcome remarks, a luxurious dinner & an awards ceremony recognizing the dedication and achievements of the physicians. Our goal was to maintain a warm, elegant ambiance for the opening segments—and our DJ Tyler delivered with meticulous timing and refined sound. Then, as the formalities wrapped up, Tyler transitioned the room into celebration mode with global hits, Bollywood favorites and crowd-pleasing dance selections.

The dance floor soared as guests shifted from applause to dancing. It’s always rewarding to see hardworking professionals letting loose—and that moment remains one of the highlights for us.

Seamless Photo Experience with Roaming Photography

In addition to extraordinary entertainment, we introduced our roaming photography service to elevate the guest experience and drive social engagement. Two of our roaming photographers captured candid moments throughout the evening:

  • Guests were greeted on arrival at a step-and-repeat where they were “spotted” or “tagged,” making a memorable entrance.
  • Throughout the event, each time a guest appeared in another photo, they received a text alert—so they knew instantly they were featured. This roaming photo experience added an interactive and modern layer to the evening—making attendees feel seen and valued, while delivering high-quality imagery for the event hosts, the honorees and the whole guest list.

By offering roaming photography alongside our DJ services, we deliver a more comprehensive and elevated event package—one that goes beyond sound and music to capture the atmosphere, the smiles and the memories.

Behind the Scenes – Teamwork & Attention to Detail

The success of this evening was truly a collaborative effort. The Rush Copley team and Hotel Arista staff worked seamlessly with us, ensuring that every element from lighting to transitions to timing was executed flawlessly.

We pride ourselves on being more than just vendors. We pay meticulous attention to every detail—so you can relax and know your event will be incredible.

Reflection & Congratulations

It’s deeply rewarding to play a role in recognizing the tireless contributions of healthcare professionals. To all the honorees at the 2025 Physician Appreciation Dinner, congratulations—and thank you for your impact every day.

If you’re planning a corporate celebration in the Chicagoland region and want entertainment plus immersive guest experience (including roaming photography, step & repeat moments and real-time photo alerts), we’d love to partner with you.

The autumn portion of wedding season is a truly magical time, particularly as late October whispers its way into the atmosphere with crisp air and vibrant fall hues. Recently, Paul Michaels Events had the pleasure of bringing sound and energy to Brooke and Michael’s unforgettable October wedding at The Lytle Auditorium in Downers Grove. This enchanting event perfectly encapsulated the essence of what a wedding should be: heartfelt, full of love, and of course, with a dance floor that stayed alive from start to finish.

The historic charm of The Lytle Auditorium provided a beautiful backdrop for what was to be a truly memorable experience. Festivities officially began after loved ones gathered to witness Brooke and Michael exchange their vows. Following the lovely ceremony, guests were ushered into a lively cocktail hour, where the upbeat music set a convivial tone and allowed everyone to mingle and enjoy a selection of delightful drinks. 

When the time came for everyone to find their seats for dinner, the excitement in the air was palpable. Brooke and Michael made a grand entrance to T.I.’s hit “Bring ’Em Out,” immediately electrifying the room with their infectious joy. This seamlessly led to their cake cutting, enhanced by the sweet melodies of James Taylor’s “How Sweet It Is (To Be Loved by You),” a selection that perfectly captured the sentimental essence of the moment. The couple shared their gratitude with a heartfelt speech, followed by a blessing delivered by Uncle Charlie. This emotional interlude welcomed the communal dining experience, as dinner was served family-style. This setup not only complemented the auditorium’s warm and welcoming atmosphere but also ensured that everyone felt connected and part of something special.

With the evening transitioning from dinner to dance, the spotlight turned to Brooke and Michael for their first dance to the calming and lyrical “Evermore” by Hollow Coves. This tranquil moment was a serene prelude to a night intended for celebration. Brooke and her father showcased a touching father-daughter dance with Heartland’s “I Loved Her First,” while Michael’s dance with his mom to “A Song for Mama” by Boyz II Men added another layer of emotion to the night, leaving barely a dry eye in the room. Once dessert and coffee were served, the stage was set for a night of dancing. DJ Tyler curated a playlist full of wedding classics and the couple’s favorite hits that kept the dance floor alive and kicking well into the night. From Earth, Wind & Fire’s “September” to alternative beats by All American Rejects, Fall Out Boy, and Paramore, every guest found themselves immersed in the rhythm, proving once again why having a skilled wedding DJ is crucial for an unforgettable reception.

As the evening unfolded, it was evident that Brooke and Michael’s wedding was a beloved celebration. Their dance floor mirrored the happiness and exuberance of the occasion, with guests of all ages joining in to show off their moves. The smiles and laughter, captured throughout the night, told a story of unyielding joy and collaboration between two families uniting as one. At Paul Michaels Events, we believe that every wedding should be as unique as the love it celebrates. This evening was no exception, and it was a privilege to be trusted with curating these special moments for Brooke and Michael. The newlyweds’ vision was brought to life with precision and passion, making it an event that not only they but everyone present will cherish for years to come.

As we close the chapter on this beautiful event at The Lytle Auditorium, we extend heartfelt congratulations to the newest Mr. and Mrs. on the start of their journey together. It was an absolute joy to share in this special day and to witness the love that no doubt will guide them through their future together. To our newlyweds, thank you for choosing Paul Michaels Events DJ Company to bring your musical dreams to fruition!

October is typically one of the busiest months of wedding season, and with the season comes some of the most memorable events that we have the pleasure of being a part of. Emily and Dan’s wedding was no exception to this! Held at the vibrant Lacuna Lofts in Pilsen, Paul Michaels Events had the honor of providing exceptional DJ services for this unforgettable occasion. Our wedding experience package, plus ceremony services, uplighting, and a subwoofer for additional audio coverage ensured that everything would be on track to make this the best day ever for our bride and groom.

The wedding ceremony took place on the rooftop of Lacuna Lofts, where guests were treated to breathtaking views of the Chicago skyline. Immediately following, guests were invited to the Magic Street room on the first floor for a delightful cocktail hour. When the time came to transition to the Reverie room for the remainder of the reception, DJ Paul Michaels and Assistant Evan had the party atmosphere perfectly set. Our full room uplighting, glowing warmly in amber hues, accentuated the rustic charm of the venue and created a welcoming and elegant ambiance.

The reception kicked off with some epic introductions. The wedding party entered the room to “I Gotta Feeling” by the Black Eyed Peas, and kicked up the energy in the room. When the bride and groom stepped into the space to “Crazy in Love” by Beyonce and Jay-Z, it was clear that there couldn’t have been a better fitting song for them. From their entrance, Emily and Dan went straight into their cake cutting, and then made a speech thanking all of their loves ones for joining them for such a special occasion.

Once dinner service was completed, inclusive of heartfelt toasts and the “Mission Impossible” game, it was time to ignite the dance floor. Kicking things off were the first dances shared between husband and wife, mother and son, and Emily’s side of the family. Once the dance floor opened for everyone to join in, DJ Paul led the charge, ensuring that every moment of the evening was filled with joy and energy. For every wedding we DJ, we make sure that each dance floor becomes personalized and memorable. For Emily and Dan, that meant including their favorite songs from Green Day, which brought an extra touch of excitement and nostalgia to the celebration. By blending their musical preferences with a variety of other genres, we kept the energy high and the spirits even higher. The dance floor stayed packed as Emily, Dan, and their loved ones danced under the captivating lights.

Thank you to Emily and Dan for choosing us to be a part of your beautiful wedding day. It was an honor to work with you and we appreciate the trust you placed in us to make your special day truly unforgettable. Cheers to the happy couple!
