Planning an unforgettable birthday party is fun in theory. Then come the decorations, activities, tables, favors, setup, cleanup... and suddenly, it’s a lot.
That’s where Katie’s Party Lab comes in.
Based right here in Erie and serving families throughout Denver, Boulder County, Northern Colorado, and surrounding communities, Katie’s Party Lab creates beautifully styled, hands-on celebrations designed to wow kids without leaving parents to pull it all together themselves.
Think less “party rental company” and more one-stop party experience. From the theme and décor to the activities, rentals and finishing touches, their team can transform a celebration into something pretty magical.
"Every event is thoughtfully planned, age-appropriate, and customizable — right down to the activity sheets and welcome signs — making your child’s party feel as special as they are." - Katie Semenas, Owner

🎈 Need More Than the Activity? They Do That, Too.
Katie’s Party Lab can take a party well beyond the entertainment.
Families can add luxury picnic setups, balloon décor, backdrops, personalized signage, favor displays and other styled details to bring the entire celebration together.
Need the actual furniture? They have that covered, too, with rentals including children’s tables and chairs, premium white kids’ tables, adult tables and chairs, luxury picnic tables, floor pillows and specialty party furnishings.
And those rentals aren't just for birthdays. They can also be used for baby and bridal showers, school events, family celebrations, corporate family events and community gatherings.
✨ Want Someone Else to Handle...Everything?
Yes, please.
For families who would rather hand over the Pinterest board and actually enjoy the party, Katie’s Party Lab also offers full-service party planning and design.
Their team can help develop the theme, source décor, coordinate vendors, style the space and manage event logistics, whether you're planning an intimate celebration for six kids or a much larger event.
The end result? A party that feels thoughtful, cohesive and special, without Mom or Dad spending the entire celebration running around making sure everything goes according to plan.
💕 More Memories, Less Party Stress
At its heart, Katie’s Party Lab is about creating celebrations where kids can make something, experience something and connect with each other while parents get to be present for it.
Every event is intentionally designed to be beautiful, engaging and memorable, with the details handled by a team whose job is quite literally to make celebrating easier.
And with everything from teepee sleepovers and spa days to slime, pottery, charm bars and full-scale custom parties, the hardest part might just be convincing your kid to pick one.
