Professional Experience

I began practicing internal medicine in the year 2004 after completing my residency in internal medicine at the Long Island College Hospital in New York. I became board certified by the American Board of Internal Medicine in the year 2004.


After graduating from medical school, I became the first physician in my family. I decided at a young age that I loved science and wanted to enter the medical field. After many years of hard work, I am glad I chose this path.

My medical scope encompasses comprehensive management of complex chronic conditions, emergency services, hospital and hospice care. My dedication to the well–being of my patients is evident in the care and support I give to them. I always take a precise approach to my consultations to ensure that I am consistently giving accurate diagnoses developing the most successful care plans. I also work at Banner hospitals and Abrazo Hospitals.

Some of the disorders that I have managed or treated include Diabetes, Hypertension, Allergies, Dementia, Chronic Kidney Problems, sexual dysfunction, irritable bowel syndrome, and weight management. No matter how and where I practice medicine, I will strive to give my patients high quality, comprehensive medical care while recognizing their needs as individuals and as members of a family and community.
