Excellent Doctor, friendly Staff and welcoming atmosphere. Dr. Mercado is very caring, thorough, and very professional. I had chance to meet Dr. De La Vega as well, they both are very attentiveness to their patients. I went to Dr. Mercado with multiple problems, including life long allergies, asthma and skin related problem. Dr. Mercado’s knowledge of regenerative medicine, hormonal therapy, allergies – skin and cosmetic medicine is outstanding. I highly recommend Dr. Mercado to everyone.
