Our History

Advanced Dermatology and Skin Cancer Institute (ADSCI) was founded by Michael Lin, MD in September 2002. He started the office by subleasing space in an internal medicine office in Tarzana, near Tarzana Regional Medical Center. After one year, he outgrew the office and started his own office in Encino at West Valley Medical Center. Dr. Lin practiced dermatology for 3 years in Encino before moving to his current office in Sherman Oaks. He custom-designed the office to provide the most advanced technologies and facilities, including a AAAASF accredited and Medicare certified surgery center, electronic medical records, narrow band UVB phototherapy booth, and many medical / aesthetic lasers. As the practice grew, other dermatologists, nurse practitioners, physician assistants, nurses, and estheticians joined the practice and several satellite offices were opened.  Today, ADSCI is one of the leaders in providing the highest level of dermatology care to the Southern California community.
