Schedule Appointment

Practicing internal medicine and gastroenterology for over 40 years has been incredibly fulfilling. My specialties include managing conditions such as nonalcoholic steatohepatitis (NASH), acid reflux, and Helicobacter pylori (H. pylori) infections.

With extensive experience and continuous engagement in new research and treatments, I strive to offer my patients the most advanced and effective care, and support. I believe that fostering strong relationships with my patients is essential for effective healthcare.

Throughout my career, I have been committed to proactive healthcare engagement and medical education. My background includes significant contributions to acid reflux and H. pylori research, including leading the early stages of drug trials for proton pump inhibitors (PPIs), which remain a standard of care today.

I have also had the privilege of teaching internal medicine residents and gastroenterology fellows, an experience that has been both gratifying and enriching. My dedication to education was recognized when I received Teacher of the Year award, a testament to my commitment to advancing the next generation of healthcare professionals.

My journey into medicine was driven by a passion for building personal relationships with my patients and the opportunity to use my technical skills for diagnostic procedures. The dynamic and evolving field of gastroenterology continues to inspire me. My education and training have equipped me with the knowledge and expertise to provide comprehensive and coordinated care, ensuring that my patients receive the highest standard of treatment.
