Dr. Dizon is a proud graduate of the UC Davis School of Medicine. He has been practicing internal medicine for over 25 years and has worked for over 17 years in emergency medicine departments in the Central Valley.

Dr. Dizon believes the best part of medical practice is the doctor-patient relationship. Each patient is different, with their own set of ideals, fears, and cultural values. After a long career as a full-time faculty professor of medicine with UCSF Fresno, he retired and founded Dizon Medicine with his wife, Nhuha. They both believe in giving back to the community and formed their practice values based on community service, teaching and quality improvement.

They are also blessed with eight beautiful children. Their whole family enjoys volunteering, tennis, golf, making and playing music, and simply hanging out.
