I love this practice. I have had interactions with Dr McAllister and Nicole. They both awesome and patient. They listen and really try to help you with whatever you're going through. I first met Dr. McAllister when he was in Milford prior his move. I followed him to Stamford and now to Westport all the way from West Haven. They're the best !!!

I drove some distance to see him and it was well worth it! Dr. Peter McAllister was incredibly patient, attentive, listened carefully, and answered all my questions, making me feel at ease. He took the time to explain my diagnosis and options in a friendly, easy-to-understand manner without being pushy. The staff was also professional and helpful, making me feel my concerns were valued.

Dr. McAllister has been the first neurologist I’ve ever seen, and I feel incredibly grateful that I found him. From my very first appointment, he treated me with compassion, respect, and genuine belief — something I hadn’t experienced with many other doctors in the past.
Instead of brushing off my symptoms or minimizing what I’m going through, he took everything seriously and has been truly committed to helping me find answers. He listens carefully, explains things clearly, and makes me feel supported every step of the way.
For anyone who has struggled to be heard in the medical system, having a neurologist like Dr. McAllister is life-changing. I can’t recommend him highly enough.
