LifeStance is a great resource for anyone looking for a counselor or psychiatrist. Their online services are great, I love the fact that I don’t have to waste time driving to and from offices. My current therapist is someone I look forward to making a connection with. It’s an important part of therapy. I’ve only had one therapist not show up to our appointment. Please, please, if you need someone to talk to, please call LifeStance and they will find someone for you.

I had my first appointment with my therapist last week and it went well. The booking process was easy on their website. They take many insurances. I look forward to continual sessions!
