I have been a patient of Dr. Hennessey's since I was 21 years old, and I'm now almost 53 years old. Dr. Hennessey cleared up my acne in my 20's, diagnosed melanoma on my chest in my 30's (I have a family history of skin cancer, my maternal Grandmother died of melanoma). Now in my early 50's Dr. Hennessey is helping me with age related sun spots and other aging skin issues.
