Meet Katie

A former NICU nurse turned full-time magic maker, creative crafter, and mama of three. For years, I cared for the tiniest fighters and their families during some of their most vulnerable moments. That experience taught me how precious childhood truly is, and how important it is to celebrate every milestone, big or small.

I started Katie’s Party Lab with one goal in mind: to give busy parents the chance to enjoy those milestones without the stress of planning. From spa parties and sleepovers to creative workshops and our wildly popular patch parties, every event is built with the same care and attention I once gave my NICU babies—only now it comes in the form of celebrations, creativity, and memories that last long after the party ends.

Whether it’s a birthday, a backyard picnic, or just an excuse to gather friends, I’ll handle the details so you can focus on what really matters—being fully present and making memories with your child.

Kind Words

Jennifer A.

Katie’s Party Lab created the most magical spa-tacular birthday for my daughter’s 8th, and I couldn’t be happier with the experience. Every single detail was exquisite—thoughtful, fun, and beautifully executed. It wasn’t just my daughter and her friends who were over the moon; the adults were raving about it too!

It was one of those rare moments that felt like pure joy in real time, and I know it’s a memory we’ll all carry for years to come. If you’re on the fence about booking with Katie’s Party Lab, I can say wholeheartedly—it’s absolutely worth it. The girls had endless entertainment, I got to watch my daughter and her friends glow with happiness, and I even felt like I tapped into my own inner child.

A wonderful, joy-filled experience from start to finish. Highly recommend!

Katie was absolutely wonderful to work with! She helped plan my daughter’s sleepover birthday party and was flexible and accommodating with changes along the way. The final result was fantastic—my daughter and her friends had an unforgettable time! I highly recommend Katie to anyone looking for help planning their next party.

Absolutely worth it!
I love the big celebration ideas but then spend weeks stressing to make it all happen, only to be disappointed. Working with Katie was the best decision ever. Katie did all the work, all the planning, took away all the stress. She made things easy, went above and beyond my plans and expectations, and the kids loved it all. This will be my party go to from now on for sure!!
