Amazing Doctor! I cannot say enough good things about Dr Marcus! I have personally referred dozens to see him. I know many who all agree that he saved their life, including my own. Intelligent, great diagnostician, great bedside manner, personable, genuine, empathetic. He fixed my diabetes, metabolic syndrome, thyroid, cortisol, and I lost 157lbs in 7 months! Don't wait, call him. He could save your life!

Doesn't care about the patient , he has very low knowledge and well well behind the time . He does not understand to dose the medication properly and just wants the office visit money . Horrible experience .

Dr. Marcus has been taking care of me for more than a decade. He caught a diagnosis that other providers missed. He has been instrumental in keeping me healthy. He even answers emails in the evenings/weekends about urgent medical concerns.
