What Dr. Dinulos's patients have to say:

On time, the staff was pleasant and accommodating. Busy day for everyone but I was kept well informed with updates as I waited my turn. Doctor was friendly and had great conversation about vacations and food. Not the usual experience you get from most doctors. Actually enjoyed my visit. Big thank you to all.

Very caring I would highly recommend Dr Dinulos and his staff

Dr. Dinulos was very professional, friendly, skilled and kind. His MA Will was the same. The good Doc chatted with me to put me at ease during the numbing portion of my procedure. I didn't feel a thing! His administrative assistant Jamie is fantastic and hilarious and I love seeing her at both locations I have visited in Portsmouth and Dover. I highly recommend Dr. Dinulos (and Dr. Marka who I see annually).

Dr. Dinulos and his assistant were able to painlessly biopsy a lump threaded through muscle and obtain enough matter to deem it harmless. A very comfortable and easy process for me. I was nervous going in but found humor and relaxation through their methods. 5 stars.

I decided to have my MOHs procedure done here instead of going to Boston this time. I found the experience to be equally satisfying. Dr Dinulos is extremely competent and reassuring !! Moreover, the support staff , namely, Will Guillaume was OUTSTANDING!! He was extremely supportive and friendly. He made a TOTAL positive experience! He deserves to be recognized!!

No one even comes close to him in terms of attention to patient details and needs, in terms of respectful interaction with his patients, and in terms of clear concise information about treatment. I give him highest marks in what I look for in a physician!
