After suffering traumatic brain injury as a result of an attack and robbery 2018 I found myself in a very difficult and seemingly unescapable mental "space" that made me feel doomed. I had seen at three therapists and one other psychiatrist with the hopes of finding a solution to my problem.. Unfortunately, nothing worked and I continued suffering from PTSD,social anxiety,extreme depression, panic attacks and insomnia. I was prescribed medication that made me suicidal. My relationship fell apart and I became homeless. By the grace of God I began speaking with Will Sutton-Ohannes at Lifestance. During my very first session with him I found that he truly listened to me unlike all of the others. He made me feel like a human being instead of a number. After only three or four appointments with him I feel like a new person. He prescribed medication that actually works. I feel like the person that I was before I was attacked and my life has come back to "normal". I wish I had met him in 2022 when I felt that my life was in the pits of hell. He is an amazing soul and anybody else that has the luck of working with him is truly blessed. I totally mean that from the bottom of my heart

Dr. Will is kind, compassionate, and intelligent. He pays genuine attention to his patients, understands the many components of the treatment for the individual he is working with, and keeps track of all the strategies we have tried. He offers many alternatives to address the needs of the people he is helping. He actually listens without judging. He is indeed the most caring and professional health care provider I have worked with in my long life. He is also really nice!

Greatest most caring provider I’ve ever had the pleasure of dealing with. I’ve had a few medication changes over the past few months and he’s been there to answer all my questions during sessions and even messages I send in the portal. I feel like I can count on him to have my best interest in mind always. I would recommend others to Dr Will and Lifestance they make everything so easy.
