Dr. Alleva is a down-to-earth and extremely knowledgeable. He takes the time to understand what is going on,, explain things, answers questions, is punctual, and most important, it is clear he respects his patients. He is the most conscientious and caring doctor I've encountered.

I have been a patient of Dr. Alleva since 1990 and currently still with him. I’m allergic to so many things, he always takes the time to listen and comes up with a solution for me. I actually broke down and cried when I found out he left Holly Hill Lane.. I will follow Dr Alleva where ever he goes. I’m hoping to find out where he is now practicing. MaryAnn Minervino

Dr. Alleva's office is amazing ... amazingly bad, that is. I have never seen a ruder bunch of office workers. The place is bedlam and it is clear that the doctors sacrifice quality for quantity. The waits are interminable. I am going to go somewhere else.

After several years of seeing Dr. Alleva, I finally had to switch to a doctor in another practice. His office is horrendous, the staff uncaring. Dr. Alleva must see a zillion patients a day. He used to spend a lot of time with me, but not in the past few years. I always felt rushed. I am so much happier now with a doctor who has time for me and an office staff that is courteous and caring.
