Dr. Duggan attended UCLA as an undergraduate before heading to University of Southern California for a graduate degree. From there, he attended Tufts University in Boston for medical school before returning back to the west coast to complete a residency in Ophthalmology at UCSD. After having spent 30 years in private practice in San Jose, CA, he is happy to now call the desert his home. After taking a brief hiatus to enjoy the desert, he is thrilled to be back to seeing patients again.
