Your trust is our top concern.
We strive to keep reviews honest, trustworthy, and fair.Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.
We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.
Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.
All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.
His thoroughness and bedside manner are unparalleled. Dr. Hennessy places the patient first in all instances. I have been his patient for over thirty years.

Always willing to spend time with you and listen to issues. Does not dramatize, but clearly explains skin issues and what needs to be done.

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.
