My practioner's great... but the checkin-process for the Zoom telehealth sessions with her have become a bloody nightmare. Since I don't have sign-on difficulties for any other zoom meetings for organizations to which I belong, this has to be on the Lifestance end of things. Instructions are incomplete and/or POORLY WRITTEN. So much so, that I couldn't get signed on for an appointment several months ago, couldn't get support from lifestance and was billed for a session because I "was a no-show" !!! AND i HAD BEEN ATTEMPTING TO DO SO FOR 10 MINUTES PRIOR TO MY APPOINTMENT TIME.

Absolutely the best most thorough Clinician I have met yet. I was desperately struggling with depression and anxiety, and just coming out of the hospital. Dr Katherine Maas saved my life. I mean it. I have been a patient of hers for about 5 yrs, and I would fly across the country to see her if I had to. I finally have hope in my life again. I couldn’t have done without her often undivided attention. She never takes the short cuts. Oh! And she does Telehealth.

I’ve been coming to Lifestance Health for almost four years now and I’d have to say Dr. Maas and the staff are extremely compassionate about what they do. They are willing to help in anyway they can from scheduling an appointment to getting your records you request or whatever you need done. I’m very happy in coming here and will continue to come as long as I need to.

Lifestance Health has saved my life. I have been a patient for five years. I mean it when I say, I was at the end of my rope when my clinician started treating me. Highly recommend Kathryn Maas. For depression and anxiety. Good Practitioners are very hard to find. I’d fly across the country to see Dr Maas if I had to. Perfect fit for me.

Has helped me get through some rough times. Shows willingness to listen, responds when contacted, provides treatment options pharmaceutically or holistically if that’s what you would like. So glad I found her and enjoy working with her. Update 4/25/26- she’s gotten me through 2 terrible time periods 😂

She has been amazing ensuring that my medications are working and getting me on the right doses. She genuinely cares and takes my current life situations into account every interaction we have, and her follow up and follow through is wonderful. I'm so happy she's my psychiatrist
