Katie’s Party Lab is a boutique children's event planning company serving Erie, Fort Collins, Loveland, Windsor, Longmont, Lafayette, Broomfield, Boulder, and surrounding Northern Colorado communities.
We help busy families create beautifully styled, memorable celebrations without the stress of planning every detail themselves.
Rather than simply renting party equipment, Katie's Party Lab specializes in creating complete, thoughtfully designed experiences that make children feel celebrated while allowing parents to enjoy the day alongside their guests.
Our signature services include luxury sleepover parties featuring themed teepees and professionally styled setups, interactive spa parties, charm bar experiences, craft parties, bloom bars, picnic parties, and specialty children's celebrations.
Each event is carefully curated with cohesive décor, quality rentals, personalized details, and professional setup and takedown.
Popular sleepover themes include Enchanted, Pink Coquette, Taylor Swift Eras, Harry Potter, Wicked, Gamer, Sunflower Fields, Movie Night, Softball Divas, Blue Coquette, and more. Spa parties provide a relaxing, age-appropriate experience with satin robes, skincare activities, mini manicures, keepsake favors, and beautiful styling. Our charm bars allow guests to create personalized bracelets or necklaces while enjoying a fun, hands-on activity that doubles as a party favor. In addition to our party experiences, Katie's Party Lab offers event rentals including children's Chiavari chairs, tables, picnic tables, décor, balloon installations, personalized welcome signs, custom party details, and other enhancements that elevate any celebration.
Every event is designed with a boutique approach rather than a one-size-fits-all package.
We work closely with families to personalize each celebration based on the child's interests, age, and personality while maintaining a polished, cohesive design.
Katie's Party Lab was founded by former NICU nurse Katie Semenas, whose attention to detail, organization, and genuine care for families now extends into creating meaningful celebrations. What began as a luxury sleepover company has grown into a full-service children's event business focused on creating unforgettable experiences and reducing the stress that often comes with planning birthdays and milestone celebrations. Whether it's a birthday party, sleepover, milestone celebration, holiday event, or special gathering, our goal is simple: create beautiful, memorable moments that children will remember for years while giving parents the opportunity to relax, be present, and enjoy the celebration.
At Katie's Party Lab, we believe every child deserves to feel celebrated—and every parent deserves to experience the party instead of spending it managing the details.
