My regular doc was off sick as she was hit by a car, and I had whatever the exact opposite of pleasure is called, getting this guy as a replacement.

He walked in 2 hours late and greeted me with "who are you?" Then, he went on to slam my regular doctor ... "she only hurt her ankle" accompanied by an over-the-top eye-roll. He was in some kind of rush (how is this possible, there were like 2 people at the walkin at this time), which was fine with me because I just wanted to get the hell away from whatever negative energy this guys was projecting.
Ugh. A big nope from me. -10/10.

This doctor gave me serious creeps. I 100% agree with the other reviews. He is not a good person, honestly he seems to take pleasure in his patient's misery. I get sadistic vibes from him. When I told him I had anxiety (in general & about my bloodwork results), he saw my report & went onto to name a number of diseases I could have, thinking it would be funny to scare me. Seriously ?! He exhibits signs of toxic masculinity & false bravado, machismo. His disgusting smirking & condescending attitude is unethical. Even his photo on here with the one eyebrow raise smirk is so yucky. I think he is really wounded & has not addressed his developmental trauma & that bitterness & anger is being projected onto his poor patients. Someone should report him & his license should be revoked. He is racist, sexist, misogynistic, rude & needs tons of therapy. I hope the MCI clinic stops having him as a doctor. Is anyone reading these reviews ? MCI Clinic please get rid of him. Your clinic reviews will improve.

I think this doctor gets off on scaring patients . I went to him and he saw how terrified I was (I’m a youngish woman) and he said maybe it could be this , maybe it could be that , maybe you have this disease & kept laughing out loud. He said all this being very animated with big crazy eyes , like a villain from a movie . I told him I had anxiety but he displayed zero empathy & continued to be sarcastic & arrogant. Worse experience of my life , seriously scarred by it . I did have an autoimmune condition but he was the worse person to deliver that news to me . Very unkind & unprofessional . Should not be practicing .

Dr. Marcus was my doctor for ten years or so at two of his downtown offices. I found him very knowledgeable with issues related to my asthma and mental health. I can't recall him ever running late for appointments.

Dr. Jonathan Marcus is a dishonest and should not be a Doctor. Rude and does not know what he is doing.

Not the first time I’ve had a horrible experience with this doctor but will be the last I will continue to avoid this clinic when I know he’s working. Rude and unhelpful. Extremely unprofessional. Feel worse after appointment.

This doctor has zero bedside manner. No compassion or empathy. Spoke down to me and did not offer help or suggestions. Sadly, he falls into the category of the type of doctor who think they are above everyone else with an oversized ego. No people skills whatsoever, therefore not meant for this profession. I don’t recommend him.

Outstanding service through MCI Six Points- very likely saved my wife’s life.
