What Patients Say:

  • “Dr. Mary Theodore is an exceptional psychiatrist. I came to her despondent after losing my 15-year-old daughter and then my mother just a month later. In one intake session, she accurately diagnosed what had gone unrecognized for 55 years. With her expertise, I now have a clear understanding of my core issues, strengths, and shortcomings—an essential foundation for the deeper work ahead. 

    Dr. Theodore provides exactly what’s needed at the right moments: empathy and validation when I’m vulnerable, and stark, realistic feedback when I try to avoid the hard truths. The work isn’t easy, but in her capable hands, I know it’s a profound opportunity for growth. Immeasurable in dollars how much it means to have a psychiatrist who truly sees, supports, and challenges me. Words can’t express my gratitude.” 

    -Marc D

  • “I highly recommend Dr. Theodore. She accurately diagnosed my mental health issues (which others had missed), and got me on the correct medications that made a world of difference. I have improved greatly under her care. She is very experienced with psychopharmacology and is very thorough. She has a very high level of expertise and training, and does her job well.”

    -Katie C

  • “Dr. Mary Theodore is the premier psychiatrist in Portland, Oregon. I've been working with her for almost 3 years, and she has changed my life in the best ways possible. Her diagnosis has positively affected my marriage, family, friendships, career, and overall mental health. She is an excellent listener, and she helps patients understand their strengths and weaknesses- in a professional, sincere, and caring environment. Dr. Theodore has allowed me to grow tremendously as a person from setting boundaries, increasing confidence, relationship counseling and more. I consider her not only my doctor, but a life coach. Anxiety, depression, and worry melts away with her thorough diagnosis and treatment plan.”

    -Lindsey V 

  • “I cannot recommend Dr. Mary Theodore enough. She has been an incredible support, skillfully managing both my medication and psychotherapy with care and expertise. Over time, she has helped me gain a deep sense of comfort and confidence in facing and working through my traumas.

    Her compassionate approach and dedication to my well-being have truly made a difference in my life. I feel seen, heard, and supported in every session, and I’m so grateful for the progress I’ve made under her care. “

    -Tracey D

  • “Dr. Theodore has been amazing. She is extremely thorough in her understanding of me as an individual (medically and personally). She found solutions that previous doctors had not and I am far better for it. She is also very timely and incredibly responsive. She goes deep in her sessions and I highly recommend her.”

    -Ian C.

  • “Dr. Theodore is an amazing psychiatrist. I have been struggling with untreated mental health issues most of my life that were exasperated by my time in the military. I was seeing a VA psychiatrist when a friend of mine recommended that I start seeing Dr Theodore instead. My initial assessment was the most thorough mental health assessment I have ever received. I am so glad that I made the change. The new diagnoses and medications have changed my life. She is very responsive and I am

    able to communicate via phone or text in real time. I highly recommend her because she has learned more about me in 3 months than my old psychiatrist had in over a year.” 

    -Nathan J.

  • “Dr. Theodore brought me back to life. I cannot recommend her highly enough. I have worked with high level providers and directors of clinics. Dr. Theodore's pharmacological mastery is without compare. Additionally, I have never experienced therapy that actually helped before Dr. Theodore. She has been available to me outside of regular working hours during my most acute times. I am beyond grateful for her and would recommend her without reservation to anyone.“

    -K W

  • “Dr. Theodore has LITERALLY changed and redirected my life to a better future. 15 years ago I was misdiagnosed with just Bipolar disorder, when really I had ADHD as well. Dr. Theodore diagnosed me with both, found me medication for my ADHD and improved medication for my Bipolar.”

    -Ryan J

  • “Dr. Theodore is a fantastic, caring physician who is a great listener. She provides excellent individual care for each patient and has been an integral part of my treatment for the last 5 years.
    I highly recommend her services.”

    -Shian-Li T

  • “After being misdiagnosed for 10 years, Dr. Theodore pinpointed my actual accurate diagnosis in my first appointment. She caught that I was being under-medicated and she adjusted my dosage immediately. Within days I felt improvement.”

    -Cari D

  • “I have really appreciated Dr. Theodore’s approach to my mental health care and would highly recommend her to anyone. She is an empathetic and kind provider who I felt comfortable with immediately, and she’s very good at integrating talk therapy with medication management.”
