About
Dr. Omeed Sizar, D.O., MPH, IFMCP, earned his medical degree from Nova Southeastern University in 2017. He completed his residency in Family Practice at St. Lucie Medical Center in 2020 and holds board certification in Family Medicine. He subsequently earned certification as a Certified Practitioner through the Institute for Functional Medicine, adding the IFMCP credential to his clinical foundation.
Before founding Sizar Wellness, Dr. Sizar worked as a hospitalist attending across more than nine hospitals in five states. That experience sharpened his commitment to early intervention. A deeply personal motivation also drives his focus on preventive cardiology: his uncle died of sudden cardiac death at age 25, a loss Dr. Sizar carries with him daily. He is passionate about longevity medicine, metabolic health, hormone optimization, microbiome science, epigenetics, and cognitive health. His clinical work helps adults pursue disease reversal and reach their full healthspan potential. He offers 60-minute appointments and telemedicine visits to support that goal.
