“I just moved to the area and found Dr. Marco through ZocDoc. My first appointment was for an annual physical. He was wonderful—attentive, thoughtful, and genuinely invested in my care. He listened carefully to everything I shared, asked thoughtful questions, and made me feel completely comfortable throughout the visit. I would highly recommend Dr. Marco!”

The office is clean and comfortable and all the staff is attentive, friendly, and makes you feel at ease.

Overall, 10/10!

Dr. Marco is awesome. He walked me through all the details and helped me understand the procedures. He listened to everything I have to say about my health and was patient

Dr. Marco is fantastic. He listens, he thinks, and he genuinely cares about his patients. If you are looking for an old-fashioned doctor who believes in the art and science of medicine, look no further. In this era of "mediocre medicine," Dr. Marco is a very refreshing change. Always a positive experience.

Dr. Marco and the Nurse Eliza (sorry for the spelling) were tremendous. They were thorough and professional. The bedside manner and the feeling they cared was present throughout the experience. Give both of them a 10!
July 11, 2025Ronald P.Verified patient
Dr. Marco was excellent -he was very thorough and discerning, and asked many questions to get to the bottom of the issue. I have a lot of confidence in Dr. Marco and I am pleased to have him as our primary care doctor.
July 2, 2025Daniel H.Verified patient
Dr. Marco was fantastic. As someone who is relatively new to the area, I was looking for a primary care doctor that I can trust. While I only need to see them once or twice a year, my health is really important to me and I'm not someone who is the most comfortable medically. When I first arrived they took my blood pressure and found it to be high but allowed me to check again after waiting for a few minutes and sure enough it was within perfect range. The office was easy to find with ample parking, the staff were kind and being able to do my labs at the same place makes things so much easier. Thanks to Dr. Marco and the staff! Looking forward to my next visit.

I booked Dr. Marco as a second opinion after attending an appointment with a large orthopedic practice which left me feeling dissatisfied, uninformed about my condition and uncertain about my care. Dr. Marco was the complete opposite-he was attentive, showed concern, and was more assertive in identifying the next steps for diagnostic testing, pain management and follow up plans. My collective experience with Dr. Marco and the nurses/assistants was one of the best, attentive, helpful and positive experiences I’ve had with healthcare providers in a really long time. I walked out of there breathing a sigh of relief that I found an advocate who had helped put me on the right path to getting the care I need in what is yet an uncertain situation. Thank you, Dr. Marco.

Dr. Marco was exactly the type of PCP that I've been wanting to find. I'd been having a hard time finding an actual Dr. to become my PCP. I'm glad I gave this practice and Dr. Marco a try for my annual physical.
He was extremely easy to discuss my medical history with as he went through all his questions. He listened and was open for my questions. I did not feel rushed and he was clear about next steps.

Just moved to the area and was trying to move my healthcare down here. I couldn’t be happier with Dr. Marco. He addressed a number of my concerns and got me on my way in multiple avenues of healthcare. Definitely recommend him and will definitely bring my family here.

May 9, 2025Deborah W.Verified patient
Finding a doc can be a challenge. We all want to be heard and to understand what is wrong with us at that time and the treatment. Look no further.
This Doc Sam Marco is kind and patient and supportive. He listens, he cares and is genuine.
The staff is amazing - from checking in to the physician’s assistant to the doc.
I booked this appointment in the wrong location - and I’m so glad I did.

He is really good. This was the first time I had a physical exam where the doctor checked my ears, listened to my chest, palpated my abdomen, and checked the pulses in my extremities. He takes the time to listen and pays attention to details. Highly recommend!
