After practicing as an associate dentist from 1990 to 1993, Dr. Pacheco and Dr. Leticia Medina established their private dental practice in San Gabriel, California. Dedicated to lifelong learning, Dr. Pacheco completed advanced training in Cosmetic Dentistry in 1996 and Endodontics in 1998 at the UCLA School of Dentistry.

Passionate about sharing the knowledge and clinical expertise he has gained over five decades, he is committed to mentoring the next generation of dental professionals. Through teaching, guidance, and leadership, Dr. Pacheco continues to contribute to the advancement of dentistry by inspiring excellence, lifelong learning, and compassionate patient care.
