Dr. Ronan’s journey to becoming a premier Bay Area surgeon began at UC Davis and the Medical College of Virginia, where he was awarded the prestigious S. Dawson Theogaraj Scholarship for Excellence in Plastic Surgery. His academic rigor translated into clinical mastery; he scored in the 99th percentile on his Plastic Surgery In-service Exam and is a double-board-certified Fellow of the American College of Surgeons (FACS).
Throughout 25 years of practice, Dr. Ronan has remained at the forefront of the industry. He is not only a practitioner but also a teacher, frequently training other physicians in advanced techniques for global leaders such as Allergan, Galderma, and Suneva Medical.

Experience matters most when it comes to surgical outcomes. Having performed over 30,000 procedures, Dr. Ronan possesses an intuitive understanding of facial and body harmony that comes only from a lifetime of dedicated practice. Whether performing a complex facelift, breast augmentation, or high-definition body contouring, his approach is defined by precision, safety, and a commitment to the patient’s unique vision.

Dr. Ronan is the visionary behind the Blackhawk Surgery Center, a fully accredited, state-of-the-art on-site facility designed to provide the highest level of safety and privacy. His influence extends beyond the operating room as a member of the elite Rhinoplasty Society and the founder of the American Society of Hair Restoration. He has been repeatedly named one of the "Best Plastic Surgeons in America" and voted "Best in the Bay" by industry peers and patients alike.

Driven by a belief that reconstructive skills should be used to treat those most in need, Dr. Ronan serves on the Board of Directors for Operation Kids. He frequently travels to Central America to perform pro-bono surgeries for children with cleft lips, palates, and congenital deformities. Locally, he remains an active community leader, having served as President of the Tri-Valley Rotary and as Director of the 49ers Foundation.
