Several years ago, I walked into this place with an area on my face that was practically eating a hole in my face. Sunni and Dr. Lin promptly diagnosed it…an aggressive squamous cell carcinoma. They soon performed a Mohs surgery and removed it from my face, with almost no scarring. They also noticed that there were several other areas of concern all over my face and body that needed further examination. Being a fair-skinned, beach-loving man in my 40s, I had been careless with my skin over the years. The doctors here, especially Sunni, have thoroughly examined my face and body on each visit, and have since removed various squamous and basil cell carcinomas from my skin. After various surgeries and skin treatments over the last few years, I’m thankful to say that the cancerous conditions on my face and body are now much more under control than the day I first walked in the door here.
