I happened to make the appointment with Dr. DeCastro before I read the reviews here and was a bit concerned about what my experience would be, but both him and his team were excellent. He listened attentively to what I had to say and explained very clearly the next steps in my course of care. I’ve also seen other good reviews for him so I’d say don’t discount him over a few disgruntled patients.
