OMG, I love Dr G. This man is the schizzle, very knowledgeable and compassionate - saved my husbands life, and although it required amputation of his leg, Dr. G did an absolutely amazing job of it. Nobody expect my husband to recover from his infection and necrotic foot but Dr. G proved us all wrong and we own him so much because of it. Thank you Dr. G for all you do.

I can't say enough good things about this doctor and his practice. His office manager is thorough and professional, beyond expectations. The doctor was punctual (this is rare and much appreciated), thorough, communicated clearly, performed a complete examination and I left with absolute confidence in him. I wish I had a primary care doctor of this caliber. Excellent.

My recent experience cost me over $100. Medicare refused to pay and my secondary insurance denied payment. Gennaro "suggested" I make an appointment for a vascular test. When I arrived for this test by appointment in his office his "tech" said he did not "recommend" this test. I took the doctor's suggestion and had the test done. Well this is why I strongly encourage all seniors to clarify the "procedure is necessary" or you, too, will be paying out of pocket for a procedure "suggested but not necessary." Listen carefully.
