What Our Patients Say and Community Feedback

“Absolutely the most liberating experience i’ve ever had with a Psychiatrist , I felt heard, I felt seen, I have seen countless of Psychiatrists and I had never truly felt like someone was actually listening, analyzing and trying to ACTUALLY find a solution rather than just pick what was the easiest pick medication wise . Highly recommend 10/10”

H. Chu

Dr. Shaw was the ideal therapist for me, as someone close to the mental health field! She delivered evidence-based care with integrity, and our work empowered me to reclaim parts of my life I didn’t think I could! The way we established clear goals and tracked my progress was very helpful, and she brought care and intention to every session. This was the kind of therapy I had been wanting for years!
