He does not listen to the patient and the problems. He seems to be rather unknowledgeable for being a doctor. Towards the end of the first visit he documented I was hypothyroid even though it was in front of me l him the entire time in the records. Really did not want to hear what I was saying. I got a bit aggressive and almost walked out and he told me if I was not going to listen to him, he could not be my doctor. It would be nice if he actually listened to my issues which I don't feel I ever got across. Supposed to go back in two weeks. Will see if he gets back to me about test results. Very disappointing as I had high hopes for answers. I can't believe he is in this group of doctors???

I had such high hopes initially for this doctor. At my first appointment a few years ago, Dr. Nacasio was brand new to the practice, and although he seemed confused (about everything), he was amiable and attentive—he even walked me out to the lobby! I cut him some slack for being new, and looked forward to my next appointment a year later. What a difference a year made! He was still confused (about everything), but gone was the kind and considerate doctor, and instead he was irritable, and ranted on about the patient before me. He was snippy with me throughout my appointment. The following year when I saw him he wasn’t quite as annoyed but seemed distracted and confused (about everything). He hardly looked at me, mostly the computer screen. After 3 visits I’ve seen enough. As soon as the practice hires another endocrinologist I’ll be moving over, and hope things will finally go properly. He’s a terrible doctor who appears to dislike his patients. I wish things had improved.

Doctor is arrogant and rude. Terrible bedside manner. Felt rushed because his staff didn’t schedule enough time for the visit. That wasn’t my fault, but he was impatient with me. I have a wonderful doctor at Joslin Diabetes Clinic, but was hoping to find someone closer to home especially with the COVID crisis. It is NOT WORTH seeing Dr. Nicasio. He attacked me for asking him to communicate with my doctor (since I have complications and bad side effects with many medications—dozens across all types of medications not just diabetes—for more than 25 years) and he said he didn’t have the time. Seriously, what kind of doctor wouldn’t want input from another professional willing to give it? A self-important jerk. Was not kind or understanding, but rude to me for not remembering every medication I’ve tried in the past. Was incredibly rude to his staff too. UNKIND!!!

Didn't give me the results of a test for weeks- even though I was calling the office every once in a while to check. After discussing my financial needs (I'm a student), they called me, gave me the results of my test, didn't schedule an appointment and I never heard from them again. I had gone three times to this office to figure out why my hormones were off. Dr. Nicasio needed me to explain what an ectopic pregnancy was which was weird...but he also didn't know how to use his own software, so many of my symptoms never made it to my original paperwork. I finally called my PCP to refer me elsewhere.

Dr. Nicasio treated me like a whole person and was willing to work collaboratively with me in my treatment plan. He listened to everything I had to say, was very thorough in reviewing my symptoms/ history, and he ran all of the tests that my GP wouldn't do. He also asked me what I wanted to do, what treatment I wanted, and let me ask questions. He looked at the whole picture: my financial needs, my lifestyle, my history, etc. The receptionist is also super nice and helpful. Go see Dr. Nicasio!
