Having been born and raised in nearby Riverside CA, with parents that were both from Michoacán Mexico, he fully understands and can relate to a vast majority of PCHC’s patients. One of his favorite things to do as a clinician is to share with patients where his family is from as he feels it helps breaking the ice and is also an opportunity to talk about something other than teeth to help patients overcome any type of preconceived dental fear. He loves making patients feel welcomed and also giving them a sense of belonging.

Dr. Melgoza has a vision, not only to continue to help the dental department thrive, but to bring new energy and ideas that can help elevate not only the dental department but the entire organization as a whole. Dr. Melgoza fully understands that being successful will not only depend on the support of the management team and staff, but most importantly depend on the surrounding communities that see PCHC as their medical home because he strongly feels that that is what truly makes the organization thrive. Dr. Melgoza looks forward to working with the surrounding community for many years to come!
