Every encounter I have had with the Doctors and staff at SNHIMA has been great-- I have no complaints at all! I am VERY pleased with Dr. Hong-- every time I see him, I leave thinking what a great Dr he is. He is attentive, listens, and gives clear answers to questions. I feel like I have a great partner in managing my health!

Colleen Taylor was the BEST! Personable, funny, and friendly! She is, by far, the best experience that I've had there. She was very willing to work with me. She made me feel comfortable and cared for! Thank you!

Dr. J was terrific spent the time to necessary to examine my medical issue and provide solutions. The practice managed to get me an appointment the day after I called with my issue of concern. I greatly appreciated their accommodating my need to see a medical professional before the long weekend.

My experience with Dr. Jonnalagadda has been great visits literally from start to finish the hole staff make me feel very comfortable and everyone has smiles on there faces rain or shine and the attention to care is 2nd to none. Dr Jonnalagadda, is by far the best Dr. I've ever had due to his way of always trying to understand my ups and downs as far as my leg & back. It's the care and the decent way they treat me as a patient is why I give this office 5 's

Anne Thomassen has been my PCP for many years. I followed her from he last practice that she was at for many years. I wouldn't go to anyone else. She WILL find out what is wrong with you. And fix it! Love her!

Very pleased with my initial, comprehensive appointment with Dr. Kazakis. Answered all my questions of the day. Derry is a tad far from Nashua, but I could not find a suitable PCP locally. I am a senior with many medical "issues" and needed a physician who would treat me with respect. We are off to a good start.

Telephone appointment. Scheduled appointment- on time. Provider was friendly, easy to talk to and felt comfortable asking questions. Visit was complete reviewing health history and updating new issues. Plan going forward was discussed and reviewed with me.

Dr. McDonald 8s my new OCP. in the short time I've been with him I feel like I've found out a lot about my physical condition. He is extremely thorough and has addressed any and all issues in my history. I'm very satisfied with him.and will continue with him as long as possible.

Dr Lafleur is an excellent physician who is friendly and easy to talk to. He has great knowledge and experience that gives me confidence in putting my health care needs into this hands. Highly recommend him.

I am a patient of Dr. Paul MacDonald, followed him to SNHIMA from his previous practice. He is an exceptional provider, he is very thorough, and a complete advocate for his patients. He also has a great personality and bedside manner. I have never had a PCP that will call you at any hour of the day or weekend with results. My whole family goes to him including my husband and young adult children! I highly recommend him if you are looking for a thorough and dedicated PCP!

I am leaving Anne Thompson and SNH Internal Medicine after 12 years. I called for a referral to ortho, they made me come in even though I don't even need a referral. When I got there Anne looked at her watch while I spent a few moments explaining my sports injury. After grabbing some promotional cream they are pushing I tried to FINISH talking about my other sports injury for which I needed help and she walked into the hallway and said she didn't have time.

She has another patient down the hall with Covid. Not quite sure what a Covid patient is doing at a primary care office or what business Anne has telling me what her other patient has going on? But I do know I should be allowed to talk to my dr about more than one issue. Very rude and very unkind way to treat a patient. Is there like a one issue rule or something? Is that how your primary care dr should treat you? "Thanks for coming in, your got three minutes and your allowed one topic so make it count" Nope. I deserve more courtesy and compassion from a primary care physician. And so do you.

Dr. Fox is always thorough, attentive and compassionate. I'm pretty sure I overstayed my allocated time but I never felt rushed at all. The medical assistant was also personable and efficient.

Arrived 10 minutes early, to fill out paperwork, and only had to wait a few minutes before being called in for yearly Physical. Dr. Richard & his Nurse checked my Vitals, went over my the past year, (Covid, etc.) and completed everything in less than 30 minutes. Excellent Staff, Service & Doctor.

I always have a positive experience with Dr. Fox. Each visit she reviews my history prior to my Appointment, addresses all issues with me, as well as answers any questions. I never feel rushed. She is extremely personable, and is exactly what a primary care physician should be. Her staff is also very proactive and provide follow up in a timely manner. Highly recommend Dr. Laura Fox.

Today I had my Annuall Medicare Health Screening with Colleen Taylor, APRN. This was an exceptional visit and one of the best I have had at this facility. She was friendly, genuinely interested in listening to my answers, was patient and explained things clearly and concisely. She offered helpful suggestions I had not considered and provided useful handouts.

I never felt rushed, or that she was in a hurry. As a result I felt relaxed and cared for. I thoroughly enjoyed the visit and left very satisfied, pleased and happy feeling it had been time well spent. She is a great example of what a health care provider should be. Thank you. You are a valuable asset to your profession.

Appointment times are convenient. Providers are easily accessible by portal. Wait time is minimal in waiting room as well as in exam room. Medical assistant staff is amazing and do their job to the fullest. Providers give you full attention without feeling rushed. I highly recommend Southern NH Internal Medicine.

Anne Thomassen is so wonderful. She is kind and compassionate and always takes the time to answer any question and address concerns. I feel so comfortable with her. Since seeing her, my blood pressure is no longer high when I have an appointment. I struggle with my weight and I never feel shamed for it. Anne is a gem.

I am quite upset with the office and their lack of follow up. I have been a patient of Dr. Lafleur for years. Unfortunately I never get to see him except for a physical. I have been waiting for test results for days. I was told I would have the results that evening. I've called several times only to be told they are sending my message high priority.

I even asked them to post the results to the portal. I had to call the on-call doctor last night. He was extremely rude and indifferent. A little kindness and compassion goes a long way. And. I still do not have my results! I managed a primary care office for 10 years and would never have allowed any of this to go on. This is not the first problem I've had with them.

Otherwise I wouldn't be writing a negative review. They made some serious mistakes in handling my husband's care. This is very troubling. I've been told by the providers and manager that they have had so many complaints and they are working on "fixing the problem." The problem starts at the top.

People are way too critical. A really wonderful doctor may make you wait a little as he or she takes care and time with all their patients. I believe Dr LauraFox is that type of practitioner and she has always given me excellent care!
