Who We Are
Meet our experienced providers who are here to support you on your healthcare journey, as well as learn more about our mission, values, and commitment to exceptional patient care.

Our Mission Statement
“At Cajon Medical Group, we are a doctor-owned, family-run practice dedicated to delivering compassionate, personalized primary care to the communities we call home—Riverside, San Bernardino, and the Inland Empire—with new clinics expanding into Orange and Los Angeles Counties. As we grow throughout California, we remain deeply committed to whole-person care, operational excellence, and long-term sustainability. In addition to primary care, we proudly support our patients’ mental health in partnership with our sister company, Inland Psychiatric Medical Group. We will soon be offering integrative services—including functional medicine, IV therapy, PRP, Botox, and fillers—to help our patients feel and live their best, inside and out.”
Our Vision Statement
“Our vision at Cajon Medical Group is to grow into Southern California’s most trusted neighborhood healthcare partner—where every clinic feels like family, and every patient feels truly seen, heard, and cared for. By bridging the gap between physical and mental health through our close collaboration with Inland Psychiatric Medical Group, and expanding access to holistic wellness services, we aim to support the full spectrum of our patients’ well-being. Guided by a sustainable, physician-led model, we’re building a healthier, more connected future—one community at a time.”
