Welcome to Sierra Endocrine Associates

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, NP Morales, NP Flemming, and NP Boldt join Dr. Hawkins in providing expert care to their patients. All of our doctors are board certified in Diabetology, Endocrinology, and Metabolism.

Sierra Endocrine Associates is dedicated to providing outstanding medical care and education for patients in the areas of Diabetes, Endocrinology, Osteoporosis, Thyroid, and Lipid Metabolism (cholesterol treatment). Our members maintain an up-to-date awareness of the causes and treatments for disorders of the endocrine system. They also develop comprehensive programs to treat and/or manage these disorders.
