Sierra Endocrine Associates, located in prestigious north Fresno, California, was founded by Dr. Joseph B. Hawkins, Jr. in 1993. His goal was to build a team of highly skilled doctors, nurse practitioners, and health educators in order to better serve the Endocrine needs of the Central Valley. Today, Dr. Punzalan, Dr. Sajid-Crockett, Dr. Khanna, NP Morales, NP Flemming, and NP Reilly join Dr. Hawkins in providing expert care to their patients. All of our doctors are board certified in Diabetology, Endocrinology, and Metabolism.
