Dr. Mark S Grossman has the following 2 specialties

  • Internal Medicine

    An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
    These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.
    In addition to treating the common cold and flu, internists also treat chronic diseases like diabetes and heart disease.

  • Pediatrics

    A pediatrician is a doctor who specializes in the regular care of children, as well as the diagnosis and treatment of illness in children. Young patients are often more complicated to treat because they are still growing and developing.
    While pediatricians may sub-specialize in specific therapy areas like oncology, surgery, ophthalmology, and anesthesiology, in general, pediatricians provide services like vaccinations, health exams, and treatment of common ailments and injuries. In addition, pediatricians are trained to handle the complex emotional and behavioral issues faced by children, especially during puberty.
    Pediatricians normally see their patients from birth until the age of 18, although some may agree to treat patients into their early 20s, if requested.

One Star

I found Dr. Grossman singularly inattentive to my request for a prescription refill and even then, he got the dosage wrong. This man evidently can't be bothered to read written instructions.

Good doctor, but overbooked

I'm a little envious of the other reviewers who say they get a lot of time with Dr. Grossman... that has never been my experience. Usually I wait for 20 minutes; then I'm seen by an intern; I wait for another 15-20 minutes and then get a whopping 5 minutes with Dr. Grossman. It's so hurried, I have to bring a list with me so I don't get flustered and forget something. He seems like a fine doctor, but I do feel like he's rushed to diagnosis a few times. For example, when I had reflux, he prescribed an allergy med without any evidence that allergies were causing it. I suspect he's a good doctor at the mercy of a crazy schedule.

Dr Grossman failed to diagnose my problem. He left out essential screenings and stuck to the initial diagnosis. He prescribed medication that was harmful to my condition- as a result I have a long and painful history of maltreatment. Once diagosed no one checked...He never listened to my significant side effects and insisted on his treatment.Can't recommend him at all.

Best PCP I've ever had

I've been a patient (adult) of Dr. Grossman for 5 years. I never feel rushed during our appointments, and consequently I never walk out of his office and then think "Oh, I meant to ask him about...". He's excellent at calling to discuss test results as soon as they're back. Above all, when I recently suffered some inexplicable symptoms, he fast-tracked a number of tests/specialist consults -- this led to quickly finding an ovarian cyst which I have since had successfully removed.
