Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Great Visit!
I've been a patient of Dr. Marcotte for years. He's patient, knowledgeable, and addresses each of my issues and concerns. I highly recommend him!

Attentive Doctor
Dr. Marcotte actively listened to my symptoms, reviewed pictures and current lab work, and asked pertinent questions. He then clearly outlined courses of treatment.

Dr. Marcotte and his excellent staff took good care of me as we tested my allergy to penicillin which occurred when I was 5 years old. Every step was explained and carefully executed. Now at 77 I can say I am no longer allergic to penicillin! Wonderful news!

Great doctor, friendly staff, slow service
I have been seeing Dr. Marcotte for years, and he has always been attentive to my allergy needs and concerns. I would highly recommend him to anyone, just know that it is nearly impossible to reach his office over the phone. (If you leave a message, the nurses are very responsive and good about following up.) I was unimpressed with the wait time during my last visit. I waited about 45 minutes in the exam room for what ended up being a 10-minute visit. (I don’t recall having a long wait for my telehealth appointment.) If you’re willing to wait in person and on the phone, you’ll be rewarded with great care.

Amazing staff very welcoming got me in as soon as I got there. So I was on time for my next appointment. Dr. Marcotte was very welcoming. It was my first time he answered every question. I was able to get my allergy test scheduled with no problems. I would definitely recommend him to friends and family.

We saw Shannon Hogate as she offers to see us when Dr Marcotte is running behind with his patient appointments. Shannon thoroughly reviewed directly with my daughter (and the parents as well) the safety plan and made sure she understood what to do in an emergency situation.
