Principal Investigator
A prominent physician in Wesley Chapel, Dr. Jonathan N. Yousef is a Board Certified Family Practice Physician in both Florida and New York.
Dr. Yousef is a Clinical and Academic Instructor at LECOM and holds an active membership with the Florida Osteopathic Medical Association (FOMA), the American Osteopathic Association (AOA) as well as other accredited associations. Dr. Yousef is often invited to speak to the local medical community about the progressive techniques he utilizes in his practice and he enjoys educating future medical providers about common ailments seen in family medicine and male health alternatives.
Dr. Yousef earned his medical degree from Lake Erie College of Osteopathic Medicine in 2000. After serving as chief resident at Wellington Regional Medical Center in West Palm Beach, FL, Dr. Yousef went on to see urgent care patients at a walk-in clinic in Tampa before establishing his own practice.
Dr. Yousef works closely with his alma mater, LECOM, and South University as an adjunct professor to new and aspiring physicians, PAs and ARNPs. Dr. Yousef is passionate about teaching and enjoys instilling the values he upholds within his practice into his students. Currently he is an academic and clinical instructor at LECOM Bradenton.
In 2008, Dr. Yousef opened the doors to Lifetime Family Urgent Care. The name in itself introduces patients to the atmosphere Dr. Yousef wishes to create – a family. Although originally established as Urgent Care only, Dr. Yousef realized what he enjoys most is caring for established patients and building relationships. If you ask Dr. Yousef what he is most passionate about when it comes to his practice, he would say, “From the beginning, my dream was to provide a place of help and healing to my community. My vision is simple. I want to be, ‘your doctor for a lifetime’ for every person that walks through our doors.”
