Extremely disorganized office. Had to wait forever before being called - and only coz I said I had to leave ifhe couldn't see me in the next 5 mins as I had to go back to work. Didn't hear back after bloodwork, had to call 3 times before someone would call me - and it wasn't even the doctor. Staff was too busy with takeout choices to stay on top of patients. Doctor was distracted and obviously overbooked to give proper attention to patients.

The interaction with the doctor was fine. However, the 1h+ wait clouded the entire experience.

Everyone in the office was wonderful. The staff was kind and professional. The office itself was very outdated but nothing too worrying. Dr. Dellosso was kind, made me feel very comfortable, but was definitely brief. Only major complain was the nurse who did my blood work definitely bruised me and even the next day, it remains sore. I’ll get over it. (the office should consider those auto retracting needles for bloodwork) Very positive experience overall.

I’m very disappointed that the doctor never returned calls from the pharmacy for an alternative medicine - even after I called his office asking them to respond to the pharmacy. After waiting for several days, the after hours answering service also refused to put the request through to the doctor. A poorly run front office.

The doctor himself is great; however the staff unfortunately not organized, which resulted in 4 months of back and forth between zocdoc, my insurance and myself. Specifically, the office listed that my insurance was accepted. it isn't. I called to resolve the issue and find a suitable settlement, but they instead just sent the bill to collections. In my entire adult life, this is the first time I have had a bill sent to collections, and it's frustrating that the staff continues to say my insurance is accepted, but sent the bill the collections due to their inability to file a claim.

Very professional, kind, and emotionally intelligent. Truly cares for his patients and seems to love what he does (it shows). Wonderful experience from check in to visit and check out. HIGHLY recommend this doctor to anyone in need of a general practitioner!

Like him, the staff, etc— but it’s sort of smelly and not hugely pristine.

He was a little late, but I had the first appointment of the day, and he had issues with tunnel traffic. Once he was in, I was seen right away and everything was very efficient.

The visit itself with Dr. Dellosso was fine. I came in with a prolonged problem of what I assumed were hypoglycemic fainting spells, and he ordered blood tests, which were done quickly and in the office. When the blood tests came back normal, however, his office made no recommendations for a follow up or referral to figure out the source of the problem... Just sent me on my way to continue having the same issue. I'll find another doctor more committed to figuring out what's going wrong.

Wait time was super quick. Felt rushed because the Doctor wanted to leave for the night. Didn't check anything aside from my heart..even stayed in my own clothes. He was nice, but just felt rushed through the appointment.

Dr. Dellosso, listens to his patients about their concerns , he has an incredible way and takes his time to explain what he's going to do. He taok the time and made sure i understood. He makes it his priority explaining my procedure. He made me at ease taking his time with a smile. I was recommend by my friend who told me to go see him. He was absolutely correct. He's a wonderful person and a great doctor. Thank you sir.

He is my internist and I've been seeing him for years. I was recommended by a co-worker and I've been pleased with him and his practice since I've started seeing him. I had to go in today for an illness (vs my annual checkup) and they got me in right away. The staff is friendly and attentive!

Receptionist was rude and Dr. went through check up quickly, not asking me if I had any issues/questions. Also was 30+ minutes late, between waiting to be seen by Dr. and having issues with the cardiogram. Office is very dated. Won't be coming back.

Once I was called into the office, I didn't have to wait long for Dr. Dellosso and it was him that I saw only to draw blood. I really appreciated that as I hadn't been there for awhile, he asked me some pertinent questions and I felt as if I was being properly taken care of.

I made an appointment on zocdoc and they didn't have it on file when I got here. Waited forever. Either this app sucks or the doctor office does. Wouldn't take the risk with the office.

Dr. Is good but my prescription never got transmitted to CVS on a Friday at 4 pm. I have 2 calls into the after hours call service without success. My cvs closed st 9 and it's 8:35 now. I've had a sinus infection for over 8 days and need to get relief.
