Dr. Fuller is a highly competent and empathetic practitioner of CBT. I’ve had a very good experience with Dr. Fuller and recommended him to others.
S.B., Therapy Client
I have been regularly seeing Dr. Fuller for 4 years. He is amazing, caring, and has been instrumental in helping me through some extremely turbulent personal times over the years.
G.C., Therapy Client
Dr. Fuller has been terrific in helping me get through my own mental laundry and setting goals. What I love about Dr. Fuller is that he’s flexible. It’s not just about weight loss or “therapy” per se, it’s really what is helpful to you.
G.F., Therapy Client
I’ve been seeing Dr. Fuller for about 9 months to help me lose weight. I’ve made great progress. He really understands that losing weight and, more importantly, keeping it off, is much more complicated than just what you eat.
