Anne is the greatest PCP I have ever had. She knows me. She advises me. She cares about me and my complete health. My virtual visits are as great as my in-person visits. This woman is simply outstanding and I could not recommend her any more highly. The entire staff at SNHIMA is equally great. These people have made me healthier and happier than I have been in years.

I had the privilege of being treated by Patrick Carolan, PA-C, and I can confidently say that he is an outstanding healthcare professional. From the moment I walked into his office, I was impressed by his warm, welcoming demeanor and professionalism. Patrick takes the time to listen, thoroughly addresses any concerns, and ensures you understand your treatment plan.

His knowledge and expertise are evident in every aspect of care, and it's clear that he genuinely cares about his patients' well-being. He was thorough during my appointment, answered all my questions, and made sure I felt comfortable throughout the process.

If you're looking for a knowledgeable, compassionate, and highly skilled provider, I highly recommend Patrick Carolan, PA-C. His dedication to patient care truly sets him apart, and I’m grateful to have him as my provider.

Dr. Macdonald is an extremely knowledgeable, helpful, and caring physician. He always goes above and beyond to meet the needs of his patients. He literally once saved my life by going the extra mile to explore a symptom that other physicians had ignored.

 This allowed the application of successful measures to deal with a life-threatening disease that I didn’t even know I had. Without Dr. Macdonald’s timely intervention I would not be here to write this review today.

My first visit and it went great. The staff was courteous, prompt and very informative. My annual check-up with Dr. Schultz was professional and he was quite prepared and up to date on all my history. I had a thorough examination and he spent quite a bit of time answering all of my questions. I never felt rushed. I feel very confident in him.
