About Dr. Donna Marchant, MD

I believe that each patient is a complex individual with his/her own unique biopsychosocial components. What this really means is that I care about how you feel, how you want to be treated, how you live, and how life has affected you. I don't just treat your disease; I treat the complete you. Unlike, most modern days physicians, I do spend a reasonable amount of time with my patients and address all of their concerns. But of course, if you are in a hurry and just want me to be quick and simple, I can do that too!

Patient Reviews

Patient

I saw Dr. Donna Marchant for recurring episodes of my heart rate jumping when I stand up. She was helpful with a separate issue (GERD), but when it came to the symptoms I actually went in for, I didn't feel like my concerns were taken seriously. I described consistent, measurable heart rate spikes and asked about further testing. She told me no additional evaluation was needed and called it a clinical diagnosis, even though no autonomic or orthostatic testing was done. She also suggested a testing location that I can't get to with my transportation limitations, and there wasn't another option offered. Because of all this, I ended up having to look for care somewhere else. I'm sharing my experience so other patients with similar symptoms know what to expect.

I believe in being my own health advocate. So, I watch my weight, exercise, meditate and eat healthy (mostly, hehe). Plus, I adhere to annual checkups, and requisite health tests and screenings. An essential aspect is having a team of physicians to address health concerns. I consider myself very fortunate to have Dr. Marchant as part of my health care team. She has provided exceptional quality guidance and medical care. Importantly, I feel she genuinely cares. I respect her expertise and credentials which is complemented with her calming patient communication. I credit her for helping me prevent a possible cardiac health crisis. So, of course I hold her in high regard, and would enthusiastically recommend her.

My former cardiologist became a concierge so I spoke to where my primary doctor is at NorthWell health and they recommended Dr. Marchant . I had an aorta stenosis that became severe so I didn't wanna wait too long for treatment. Dr. Marchant scheduled a sonogram and blood work to be done . As soon as possible she had me scheduled for an angiogram which she performed herself to make sure I would be a candidate for the TAVR procedure. Shortly after I went to North Shore Hospital to have a valve replacement. I saw Dr. Marchant for a follow up --she had a sonogram done before I saw her to see all was good with the valve --- all is good thank you so much for your hands on diligence. if you need a cardiologist I highly recommend Dr. Marchant
