He felt very dismissive and not interested in my concerns. I left thinking my ongoing pains and troubles have all just been in my head and weren't a valid complaint.

Apr 05, 2024

I go to Dr. Santiago because I believe that he cares about my needs.

Dr Santiago is one of the best around. Almost our entire family (my husband's extended family as well) has him as their Primary Doctor. Very good bedside manner, and has helped me personally come along way with improving my health and wellbeing. I have finally found a doctor to TRUST.
