USF Pediatric Surgery

I'm currently working as an Assistant Professor in the University of South Florida Physician Assistant Program. On Fridays, I continue to provide care to patients that require same day (acute care) appointments for USF Family Medicine.

I grew up in California and Oregon enjoying beaches and the mountains. After high school I began my medical career in the United States Air Force as a Medic, serving at home and abroad. From there I earned my Bachelor of Nursing degree from the University of South Florida. I practiced as a bedside nurse for 5 years while going back to school to earn my doctoral degree as a Nurse Practitioner, also from USF. I then joined the team hear at USF Internal Medicine and Pediatrics where I have been proudly serving this community since 2020.

I have worked in the Department of Pediatrics at the University of South Florida Morsani College of Medicine for 10 years. During that time, I have been very involved in both medical student and resident education. Having the opportunity to be a part of the lives of my patients, students and residents is something I consider to be a great honor. I have two boys and they have helped me to become a better pediatrician. Together, as a family, we enjoy being outdoors when it is not too hot.

Dr. Khalaf is committed to providing individualized, innovative, and compassionate care for pediatric patients with gastrointestinal conditions.
