I have been using Lifestance Health since the start. I have been blessed to have gotten a extremely experienced Psychiatrist by the name Dr. Barry Mills. Since the first day I meet him he made me feel extremely comfortable talking to him. I never for one second did I feel judged by him. He and the Lifestance Health team have all been that way very caring and professional. Also I can tell over the past year that my Doctor truly cares about my health and my mental improvement! I recommend anyone in search of care to make Lifestance Health one of your options. Also they will accommodate you with your appointments. If you don't have transportation they give you the option of doing telehealth appointments which are like a zoom appt. Privately with your Doctor. So obviously my experience with their whole team has been wonderful 👍 They get 5 stars from me!!! ⭐⭐⭐⭐⭐ Thank you so much 🙏 a Happy Patient

We’re very grateful for LifeStance especially Dr. Mills for helping my brother to get better. He’s been suffering from Schizophrenia since the age of 28 . He’s now 66 years old. Dr. Mills graciously agreed to prescribe the new medication, Cobenfy, for him and we’ve already noticed some changes in him. Hopefully, he’ll continue to improve even more as time goes by. Thank you Dr. Mills.

I have been seeing Dr. Barry Mills for some time now at Psychiatric Wellness Center and I have never thought of going any where else since the first day. The whole team there meet all of my needs from my appointments, medications, Dr.'s Appointment's and anything else I may need. Dr. Mills listens to every thing that I tell him and we work together as a team to keep my treatment on track.
