What do Seattle parents say about our #1 Birthday Party

We had our son’s birthday party at Kids Science Labs, and it was exceptional. Not only was the staff attentive, energetic and friendly, but the kids had an amazing time.

Recently we held a birthday party there for my 5 year old and all I can say is wow! The kids had a blast. Their parents were very impressed with the party and Kids Science Labs as a whole

I typically do not write reviews. Don’t have the time with 3 little kids to do much less drive them all around the city for a class or party etc.....The reason I am taking the time to write one is because I had my son’s 7th birthday party at Kids Science Labs and really feel that the establishment is excellent. The teachers were wonderful, engaging, and really good with the little ones. One of the kids was shy and not participating. As a mom, I can’t tell you how endearing it was to see the owner taking the time to include a kid who was too shy to include himself. Most facilities don’t personalize the experience the way that he did. We have been to EVERY birthday party imaginable. This is truly a one of a kind experience. THANKS, Kids Science Labs and we will be seeing you again.
