Patient Testimonials

The staff has always been very friendly and helpful. Dr. Lockshin has always provided me with the best medical care possible and takes time to explain everything he does. I have been going to Dr. Norman Lockshin for years and sometimes see Dr. Ben Lockshin . Would highly recommend them to everyone.
Andrea S.
Dr. Cole is a wonderful doctor! She listens and makes me feel at ease. Dr Cole is extremely knowledgeable and professional and is also a very nice person.
Debbie M.
Dr. Ben Lockshin provided excellent medical care – a minor procedure was conducted efficiently. He answered all my questions in an informed and understandable way. Also very kind, approachable, and professional.
Sandra M.
Dr. Singh was excellent. He explained my condition, method of treatment, and was very professional and friendly.
Chloe E.
After suffering from an itchy rash for almost 3 years and seeking help from many dermatologists during that span, I was referred to Dr. Cowen , who thought I may have an auto immune disease or some type of lymphoma. Within 2 weeks I was diagnosed with Hodgkin’s Lymphoma. After the second chemo treatment I finally had relief as the rash began to disappear. I greatly admire his knowledge as a physician and wish that many other doctors would think outside of the box rather than simply treating ‘the skin’.
