Published: Wednesday, October 25, 2023

GAINESVILLE, Ga. – The heart and vascular team at Northeast Georgia Physicians Group (NGPG) and Georgia Heart Institute is growing as Samer Alharthi, MD, and Nizar Hariri, MD, recently joined NGPG Vascular Center in Braselton. Both surgeons bring a wealth of experience and skills, and they are excited to join the NGPG team.

Dr. Alharthi

“What drew me to NGPG the most was the fact that they always put the patient first in everything they do,” Dr. Alharthi said. “The group is a pillar in the community, so I’m ready to join in that and work alongside these dedicated and expert physicians.”

Dr. Alharthi graduated from Taif University in Saudi Arabia and went on to complete his surgical training at the University of Toledo in Toledo, Ohio. He went on to complete a vascular research fellowship while earning a degree in public health administration.

“I remember working with passionate and very skilled vascular surgeons during my training,” Dr. Alharthi said. “That’s what ignited my interest in vascular surgery and drives me to build strong relationships with my patients.”

Dr. Alharthi enjoys following his patients on their healthcare journey and makes it a point to ensure they get the proper care after surgery. He’s careful to follow his patients every step of the way, ensuring they have a smooth and seamless recovery.

When he’s not at work, Dr. Alharthi enjoys landscape photography. He has plenty of chances to practice as he explores different cultures and travels with his wife and daughter.   

Dr. Hariri

Similarly, Dr. Hariri is also passionate about patient-first care. As a family-oriented individual, he brings that same mindset to how he practices medicine.

“My philosophy of patient care is to treat everyone like they are my own family,” Dr. Hariri said. “I ask myself, ‘What if that was my own mom or dad?’ and that motivates me to do my absolute best to serve them.”

Dr. Hariri graduated from Aleppo University in Syria before completing his general surgery residency at Charleston Area Medical Center in Charleston, West Virginia, and his vascular surgery fellowship at Jobst Vascular Institute in Toledo, Ohio.

Dr. Hariri relocated to Georgia to be closer to family. Outside of work, he enjoys kayaking, jogging and reading with his wife.
