Daniel Di Cesare, MD, is a skilled and compassionate physician at Orange Coast Dermatology, a medical, surgical, and cosmetic dermatology practice with locations in Rancho Santa Margarita, Orange, and Mission Viejo, California. As the son of missionary parents, Dr. Di Cesare grew up helping people. “Caring for people is second nature.” So it was only natural he became a doctor.
After completing his undergraduate studies at Wheaton College in Wheaton, Illinois, he initially focused on internal medicine and pediatrics during his residency at the University of Texas, Houston Medical School | MD Anderson Cancer Center. But after a clinical research fellowship in dermatology, followed by a residency in dermatology, he knew he found the specialty for him. Research in dermatology fueled his interest in the field.
Today Dr. Di Cesare maintains memberships and certifications with several professional organizations, including the American Board of Dermatology, the American Academy of Dermatology, the American Medical Association, the American Society of Mohs Surgery, and the American Society for Dermatologic Surgery.
Dr. Di Cesare has assisted in more than a dozen studies and clinical trials for topical medications for eczema and psoriasis. These medications later received FDA approval. “Now, doctors are prescribing these medications, and they’re making a significant difference in people’s lives. It’s very gratifying to see the results of your work in research with patients.”
Helping other people isn’t limited to the office for Dr. Di Cesare, who speaks fluent Spanish. He has coordinated and participated in minority health fares, volunteered at a community clinic in Jamaica, and served a medical mission in Piedras Negras, Mexico.
Dr. Di Cesare is a team player, whether it’s as part of a team of doctors or a patient-doctor team. “Being able to diagnose a skin disorder, and successfully treat it takes teamwork.
