Our Physicians

Dr. Klein and Dr. Mraz first met during their residency at Yale, where they received top-tier training from leaders in medicine. They each went on to gain experience in medical, surgical and cosmetic dermatology, while participating in cutting edge research, and presentations locally and around the world.  In 2018, they merged their experience and passion for Dermatology and opened Modern Dermatology in Westport, CT.

As the practice has grown, Dr. Klein and Dr. Mraz have welcomed Dr. Nina K. Antonov, MD, FAAD, Dr. Marc Beuttler, MD, FAAD and Dr. Shayan Cheraghlou, MD, FAAD to the team.
