Here’s what our clients are saying:
“I feel very supported in working towards my goals, like my therapist really understands what I’m going through and how to help. I have gained a great deal of insight and actual tools I use day to day that has really improved the quality of my life.”
“I had really bad postpartum anxiety and depression and Dr. Cox was so helpful. I wish I had gotten help sooner, I was in denial and thought I could do it on my own, but after starting working together I started to see how many things I could do differently and how I was denying myself the very thing that could help me heal. My relationship with myself is much better now too.”
