I was born and raised in Palm Springs, California, and was the first child born in the city of Palm Springs, CA in my birth year, narrowly missing being the first in the entire Coachella Valley, CA by just a few minutes. As the eldest of seven siblings and the only male, I learned leadership and responsibility from an early age.

My career in healthcare began at age 22, when I started working for a small, independent medical management and billing company as a credentialing specialist. This role sparked a lasting interest in the medical field and provided a strong foundation in healthcare administration. I later transitioned into clinical research, where I worked in a retinal clinic conducting Phase II–IV blinded and double-blinded randomized clinical trials. I also participated in a Phase IV government-contracted research project, gaining valuable experience in both private and public sector clinical operations.

Seeking to expand my understanding of hospital systems, I joined Desert Regional Medical Center in Palm Springs as a temporary staff member in Business Development. Over the course of approximately 7–8 years, I advanced into several administrative roles, including Executive Assistant to the Chief Compliance Officer, and Administrative Assistant in the Quality and Risk Management departments. Eventually, I served as the Administrative Assistant for the Graduate Medical Education (GME) Internal Medicine Residency Program.

This experience led me to Western University of Health Sciences – College of Osteopathic Medicine of the Pacific (WesternU-COMP) in Pomona, where I worked for 4.5 years as the Lead Rotations Coordinator.
