  • Yes, I met Dr. Nicasio. I thought that he was very, very professional. He was very concerned. He offered me, he checked me, he had his own opinions, what he thought I might have. He wanted complete blood work, which was really nice. He wanted blood work. He wanted my urine tested for 24 hours. He gave me a small physical when I left the office. He seemed very concerned, very caring, very professional. [redacted]

    2026-08-06

  • Dr. Nicasio was ready with the full update on my year-long experience with the Evinity injections, the blood work that I'd completed, and what I needed for further care regarding my bone density.

    2026-08-06

  • He was open to seeing me again prior to my next scheduled appointment should the need arise. I. E. he expressed a willingness to fit me into his busy schedule if necessary.

  • I would have liked more info about how to interpret all the labs and tests and what some outcomes might mean

    2026-08-01

  • So this was my first time actually seeing him and to his credit he spent probably a little over an hour going over everything with me and my parents. Their English is not great. They mainly speak Spanish and thankfully he speaks Spanish so he was able to explain things in a way to them that, you know, they, it was coming directly from him so they got it. And, you know, he speaks fluent English so he was able to speak to me. [redacted] He listened to everything I had to say. It didn't feel rushed. He gave me all the information I needed. And overall, I knew most of what he was going to say, but I walked out of there very, very happy. Yeah, no complaints for me. Him and [redacted] and the receptionist were amazing.

    2026-07-31

  • He was attentive, thoughtful, caring, and didn't make me feel rushed. In the very few instances when I didn't understand what he was saying, he stopped and explained it in terms I did understand.

    2026-07-18

  • The doctor listened to my history, though didn't get all the details right. He gave plenty of time for listening. But his descriptions of possible medications was abrupt and far from complete. It was highly inadequate, as he left me with the impression that I have to choose what medication I go on-and there was very limited information on how to make that choice.

    2026-07-17

  • Knowledge is the key. The doctor was very knowledgeable.

    2026-07-17

    2026-06-22

  • Unfortunately I did not have a good experience with Dr Nicasio. He did not know much of my medical history, spoke over me several times and also dictated into the computer instead of giving me eye contact or speaking to me directly. He made me feel a bad about not getting certain blood tests and blamed my surgeon for the way my surgical results were presented but made it my problem. [redacted]

    2026-03-08

  • I really like Dr. Nicasio. We get along well. I didn't get along well with my endocrinologist at Bay State, and we always argued about the meds, and Dr. Nicasio really understands why or how I should be treated, I feel. But he does it very efficiently, but he's also very friendly, and he's got a good manner, like I feel like even though I only see him once a year, he remembers me from last year, which is fine. So it's all good. Thanks. Thank you.

    2026-03-09

  • Great care

    2026-03-04

    2026-03-03

  • Absolutely enjoy Dr Nicasio and his team

    2026-03-04

  • My only complaint with Dr. Nicasio is he speaks really fast and in medical terms. I'm a nurse so I'm able to catch a lot of it, but I think if I didn't have a healthcare background, I would have no idea what he's talking about. Between the speed of which he talks and the acronyms he uses or whatever, the language, I just think he needs to dumb it down a little bit. And even me having, you know, knowing a certain amount about what he's talking about, I wouldn't mind having it dumbed down for me as well. I think that's the best way to reach the most people. And that is it. Thank you.

    2026-03-04

  • too focused on endocrine cause of health problem and didn't want to consider rheumotology contributing to health problem

    2026-02-15

  • I don't usually have issues with this provider. Although I will say it at this appointment, his staff seemed a little scatterbrained. Meaning my lab results were not uploaded into my chart so twice he had to go out of the room to ask them to do that task.

    2026-02-14

  • [redacted] I really like and trust Dr. Nicasio. He listens, answers my questions and seems very curious, intelligent and knowledgeable to me.

    2026-02-12

  • The provider is excellent. [redacted]

    2026-02-11

  • I've been going to Dr. Nicasio for about five years and he's always on top of his game. He figured out something that two other doctors could not figure out. I have a dual diagnosis of Graves disease and Hashimoto's. He's got me on meds and we've got them stabilized and I think he's doing a terrific job. And his quote unquote bedside manner is awesome. He's just a really good dude. I appreciate you guys and I couldn't ask for better service.

    2026-02-27

    2026-02-04

He also brought up questions on why my pcp is not addressing some issues I mentioned to him! So happy I found him and patiently waited more than 5 months to see him!

    2026-02-04

  • He always listens and takes the time to explain everything to me. He even gets excited about my health progress. He is my favorite provider.

    2026-02-05

  • He did not care to listen to me. The provider spent most of his time dictating the visit.

    2026-02-04

  • Dr Nicasio appears to be an extremely well informed doctor. He took great care to help me understand a very complicated process. He researched and calculated data to determined the best course of action. He provided me with printed instructions which I appreciate since I am [redacted] years and need explicit directions. I am amazed at his abilities. I am fortunate to be his patient.

    2026-02-02

  • Very positive

    2026-02-02

    2026-02-01

  • He explains things to me and provides a copy of appointments and tests I need to have.

    2026-01-28

  • The Dr. is stressful and difficult for me to talk to. He doesn't so much talk to me, he talks about me to his digital recorder. So far my appointments have felt really rushed, and I find it difficult to ask questions. He is polite, and I appreciate the care I have received. Unfortunately I would dread needing to have more complex conversations with him. As it is, my very simple medication needs haven't necessitated much and even that has been a bit off putting. [redacted]

    2026-01-28

  • Dr. Nicasio was very straight forward. It was obvious he had already looked at my chart and referral. He was easy to talk with, and sought to partner with me, not talk at me. The referral to a surgeon was prompt, ordered lab tests were explained thoroughly. He gave good instructions, and explained the medications available, which he was choosing for me and why. I left with 16 pages of printed informational material. There was nothing lacking in my experience with Dr. Nicasio.

  • Didn't need to see me. Just sat as he calculated the results he had from prior mri.

    2026-01-14

  • Recently moved to MA from [redacted] so I was referred from PCP and a new patient. The Dr. was very good, to the point, understood my answers and when dictating to his device heard me and adjusted when I heard interpretation gaps. On the occasions I asked "what does that mean" he told me in a way I could understand. I was referred to CD Hosp for a minor procedure and we discussed what I should expect and was scheduled for followup in 4 months to review and determine next steps.

    2026-01-12

  • Because I just moved to Western Mass [redacted], this was my first visit with Dr. Nicasio. The staff was very helpful updating my medical history and prescription medications. Dr. Nicasio was attentive and knowledgeable regarding my condition. He was thorough with his explanations and provided written notes and instructions. I am very happy to have found him as I feel he is providing excellent testing and follow up care so far.

    2026-01-12

    2026-01-09

  • MD looked at reports toward end of visit. I did not feel that my condition was adequately addressed. Did not feel reassured of condition and symptoms [redacted]

  • He treated me like I was disgusting because I smoked cigarettes, and to him, I stank. He started telling the nurse to leave the door open, and when the nurse came back, he said, "Because of this smell, now I'm going to have to open the window." I didn't like that because there are many patients there with different smells, and I worry that he treats them the way he treated me. Thank you very much.

  • Dr. Nicasio is most professional, thorough, knowledgable, compassionate, and extremely intelligent. In addition Dr. Nicasio interpreted all the sonograms while reviewing the sonographer's measurements and data. He is a brilliant physician, I am most grateful he is my endocrinologist.

  • He does an effective job, an exceeds expectations!

    2025-11-27

  • Was an excellent appointment. Easy and relaxed

    2025-11-26

  • I was in the room waiting for 30 mins and was seen 20 mins. He stated " i have to go as i have a new patient ".. and i thought " what about me ?" .. he never asked me if i have other concerns that needed to be addressed.

    2025-11-26

  • He was very thorough, even palpated my neck (thyroid) and did some other physical tests and explained them. Its so rare that doctors give a decent physical exam, rather then just asking questions.

    2025-11-23

  • Dr. Nicasio is very comprehensive in asking questions. I felt I had time to update him and all my concerns about meds and also about a change in a med, which was very important. He listened carefully, took down my symptoms and changes, and re-prescribed the medicine. I went to the pharmacy the next day and everything was all in line. I really appreciate his care. He's very, very caring and concerned and answers all your questions. Thanks.

  • Nice person, he goes beyond expectations.

    2025-11-22

  • The provider was an expert in their field but the visit was rushed and they spent much time verbally communicating to computer for info for me to take home etc. and to document my visit! Very impersonal [redacted]

    2025-11-19

  • Although he was 1/2 hour late he did apologize for being late.

    2025-11-19

  • I liked this Doctor when we first started. He was very patient & answered the many questions I landed on him. After further appointments he seemed very very rushed, was not as patient as before [redacted]

    2025-11-16

  • Very thorough and knowledgeable in the field. Best Doctor I've seen in years

    2025-11-15

  • He did a very through review of my medical history, and explained my on-going treatment.

    2025-11-15

  • It was not his fault about knowing my case - apparently my general practitioner had not sent any info about my medical history

    2025-11-12

  • The Doctor is well equipped in his medical knowledge. I was well pleased in his experience and understanding of diagnosis of treatment and care. I would trust his opinions in understanding my own circumstances better. If I had any criticism, it would have to be that I felt his irritation with me regarding how long I, myself, took to see him for my follow up. It was mentioned to me several times. [redacted] The Doctor was wonderful, having seen him, but I would maybe encourage him to be a little more understanding and practice patience in regards to people's lives and abilities outside of his office. Overall, I believe you are quite fortunate to have him on staff.

    2025-11-12

  • I have had doctors before for my diabetes and they treat you like a number. This doctor actually listens when I say something. I'm very happy with him.

    2025-11-12

  • I'm very happy with the care I'm getting from Dr Nicasio. He is super knowledgeable, a good listener and genuinely a very nice person.

    2025-11-16

  • He was very interested in what I had to say and asked lots of questions and listened to my concerns. I found him to be thorough, attentive and friendly.

    2025-11-09
