"I’m glad I found Dermatology Associate! And right here in Hercules. I came in primarily for acne issues. All the physicians, for initial and follow up visits, whom I’ve met have addressed my concerns and I’ve seen a major improvement! They’re great at providing concise instructions and recommendations for me to follow through. Only issue that could be a problem is I have yet to see the same doctor for my follow up visit. However, all the doctors know what they’re doing and understand my concerns that I don’t have an issue with this! Would recommend!"
