Patrick J Brennan, MD, PhD

Dr Brennan is fabulous. He's always totally engaged when you meet with him and pro actively tries to improve your current allergy condition. I've never been rushed through an appointment plus is always available through the portal. Excellent "bediside manner"! Since I've reacted to some of the shots, I make my appointments on the days he's at Foxboro (his request) and he's a step away if I need him. It's reassuring and I greatly appreciate his oversight. All you want in a doctor.

Extremely thorough, caring, and responsive

Dr. Brennan was very thorough in obtaining my medical history and in listening to my answers and concerns. He explained things well and provided details for the reasoning behind his thinking and the most likely causes of the skin irritation I have been experiencing. He also provided helpful tips and treatments to try to alleviate the condition.

Excellent in every respect!

Dr. Brennan is awesome... knowledge, friendly, and warm. I wish all my doctors were like him.

He was exceptional!

Not that it was happening, but somebody should go out of their way to appreciate this guy. I had two other appointments in the past where they go for the most and make it a big deal. They didn't really get much out of it. This guy went above and beyond. I don't really know how he does it because he's getting into New York City and a bunch of good stuff. It was a very calmed out. So it's not the band raid, but it was excellent. It's what you would want from a doctor's appointment.

Very kind and patient and explained things really well and I definitely want to go back.

1st meeting. Very thorough. Explained next steps.

I as there only for allergy shots but had a reaction to them and needed Dr Brennan as well as [redacted] the nurse as they had to administer an EPI pen treatment. Couldn't be happier with the care and attention over 90 additional minutes I was there. 5 stars for both.

He can't diagnose my problem, so is recommending me to a specialist who hopefully can.

Dr. Brennan was kind, thorough, helpful, and knowledgeable about my various allergies. He made good suggestions about treatment. He is the best doctor I've ever seen in the area of allergies.
