I’m not from the Seattle area and am visiting for about a month. I’m actually a current StretchLab member in my hometown and have had such a great experience there that I left them a five-star review. Unfortunately, my experience with the Mercer Island location was the complete opposite.
While scheduling online, I accidentally booked my appointment at the Mercer Island studio instead of another nearby location. I didn’t realize my mistake until I arrived at the other studio. As soon as I discovered the error, I immediately called the Mercer Island location multiple times asking for someone to call me back so I could cancel. Because of the distance and Seattle traffic, there was simply no way I could make it to Mercer Island in time.
When I finally reached someone, I was told, “That’s our policy. There are no exceptions. There’s nothing we can do.”
I asked to speak with the manager or owner because I hoped someone would exercise a little discretion. Instead, I never received a phone call—only a text message saying there was nothing they could do.
I disagree. There was something they could have done. Policies exist to provide consistency, but good customer service also allows room for common sense and compassion. This wasn’t someone repeatedly missing appointments or canceling at the last minute out of convenience. It was an honest mistake by an out-of-town customer who called immediately after realizing the error.
As a business owner myself, I understand how important appointment policies are. My own business depends on people showing up. But I’ve also learned that occasionally extending grace to someone who makes a genuine mistake builds far more goodwill than rigidly enforcing a policy.
My warning to prospective customers is simple: if you book with the Mercer Island location, be aware that there appears to be little flexibility if you make an honest scheduling mistake. Based on my experience, don’t expect understanding or an attempt to help find a reasonable solution.
It’s disappointing because I know firsthand how great the StretchLab brand can be. Unfortunately, this particular location fell far short of the customer service I’ve come to expect.

I live all the way in North Bend and drive to Mercer Island every other week to see Arathi. She is amazing and always fixes me. I workout 5 days a weeks and run 4-5 times a week. Every time I see her, she re-aligns me! Will continue to see her and so worth the drive! Been seeing her for 4 plus months now.

I have been going to StretchLab on MI for a while now and have noticed a big difference in my flexibility. Arthi is frequently my flexologist and does a great job. She is very knowledgeable and listens to my areas of concern. I always feel great after our sessions.

Been going here for roughly 3-months. Ashley has been my regular go to and she’s been fantastic. She’s great at landing into that sweet spot without over doing it.
