Michelle Welch

Medical Doctor

A native of California, Michelle earned her Bachelor of Science degree from Pepperdine University and attended Albany Medical College in Albany, New York. After earning her Doctor of Medicine degree in 1997, Michelle moved to Texas to complete her Internship and Residency in Internal Medicine at the University of Texas Health Science Center at San Antonio (UTHSCSA). It was there that Michelle developed a deep interest and passion for the field of Endocrinology, due in large part to its prevalence in the community she now called home. This interest led Michelle to complete a fellowship in Endocrinology, Diabetes, and Metabolism at UTHSCSA in 2002, and eventually, she founded her own private practice. Her desire to improve community health and utilize the latest diagnostic modalities and treatments continued to increase, and Michelle became involved in Clinical Research. As her work as a Principal Investigator in research continued, she quickly earned the recognition of her peers for her clinical knowledge and patient-care compassion. She has since been nominated and holds multiple Advisory Board positions. She is a sought-after speaker for major pharmaceutical companies. In her personal life, she enjoys spending time with her family and riding her horse, Kinsman.
