See what our patients are saying about Margaret Yoon

I found Dr Yoon and how my appointment was conducted to be very professional and serious consideration to maintaining my privacy. I'm very happy with my intial meeting with Dr. YOON and the LifeStance Health patient portal. This site provided me with various doctor profiles that helped me to search for a new psychiatrist after 13 years with my current Doctor retiring in December 2025.Dr. Margaret Yoon's medical profile and bio stood out to me and after my first appointment with her I feel confident that she is the right choice for me. She was compassionate, understanding and eager to listen to mu history and concerns. This has been a very positive experience and I highly recommend them based on my current experience.
