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.

Kind, Caring, Knowledgeable and Attentive
Dr. Terrana is a fabulous physician. He is kind, caring and most importantly knowledgeable. I have been a patient for over 10 years and he is the best. I recommend him to all family and friends!

I just started seeing Dr. Terrana for diabetes. So far I can tell you I am thoroughly impressed. I was sent a script to have bloodwork done prior to my first appt. My results were reviewed & I received a call from his office to change my appointment to an earlier date. I was away with my family and became concerned about my test results. I called the office back & explained my concerns- I asked if the Dr would possibly call me back to discuss my lab results. The woman said she would leave him a message. I was grateful but since I was not an established patient I doubted he would call back. Well, 6:30 PM that Friday evening my phone rang and it was Dr. Terrana. When a Dr. cares enough to call a non established patient after hours because they feel apprehensive - that’s the Dr. for me. I just recently went in for my first visit and feel very confident in the Dr. & office. I’m looking forward to getting better and having Dr. Terrana as my endocrinologist.

I’m so happy I found this office. After a terrible experience with an endocrinologist I was so relieved when I met Dr.Terrana and his staff. The woman up front are usually so nice on the phone and in person. Dr.Terrana took the time on my first appointment to explain to me what Graves’ disease was. He even printed me paperwork to take home to understand it further. I didn’t feel rushed and he gave me options on how to help my hyperthyroidism. It’s been over 3 years and he has kept my levels in range and I always recommend him to anyone needed some answers or help!

Robert Baffa in Port Jefferson – Aug 06, 2019

Several months ago I left a terrible review for Dr. Terrana. It was completely misdirected anger. I had had my thyroid checked for the last five or six years, and was assured it was not cancerous. The goiters became so large I went to a surgeon, Dr. Brian Untch Who agreed that it was not cancer. My thyroid was removed by Dr. Untch and nine days later I got news that in fact it was cancer hidden in my massive goiters. . I was mad, and hurt. No one could have seen that I had thyroid cancer. I completely retract my first review against Dr. Terrana because it was no fault of his. It was a second cancer diagnosis for me, the first one being breast cancer. I did not continue to see Dr. Terrana for six years because I thought he was a terrible doctor.he is wonderful. His waiting time in his office is minimal his staff is extremely courteous, and Dr. Terrana remarkable. I do hope he excepts my apologies, and I recommend anybody I know to go see this wonderful doctor. Thank you Dr Terrana

Dr. Terrana is one of the most compassionate, patient, & patient advocate doctors that I have met. From day one 10 years ago, Dr. Terrana and his staff has answered every question I have & was the only Dr. that would prescribe a not popular big money maker medicine that works for me. I was so happy with him I sent my daughter to him, who for 5 years had almost lost her life after thyroid cancer surgery, because doctors did not listen to her. Thank you Dr. Terrana & your kind professional staff

Dr. Terrana is a kind, compassionate, knowledgeable doctor. I was in search of a new endocrinologist and I needed an emergency appointment. His secretary did everything she could to fit me in immediately. He made me feel so comfortable and was very thorough with how he explained various things to me. He spent almost an hour going through everything during my appointment. I would highly recommend him.

I went to Dr. Terrana for a second opinion, since my last Dr I was not satisfied with. I'm so happy I found Dr. Terrana, he is the most passionate, caring, understanding Dr. I have ever met. He makes you feel so comfortable and definitely takes his time explaining things to you. I wish all my Dr.'s were like him. I couldn't have asked for a better Dr. I HIGHLY RECOMMEND him, I am so upset I wasted my time with the first Dr. just because the office was close to home.
