Jennifer L. Acosta, MPAS, PA-C

Jennifer was born and raised in South Texas. She graduated with her bachelor’s in Health Education from Texas A&M University in College Station…WHOOP! She then graduated with her Master’s degree from the University of Texas Health Science Center at San Antonio. Jenny has been happily married to Eddie since 2012 and they’ve recently relocated from Laredo, TX. She is an avid runner, yogi bear, dancer, and friends claim she is a “chef” at heart. She enjoys spending time with family, friends and her adorable Cockapoo Tungsten.

Care Philosophy:

Jennifer takes care of all ages, although she has a special place in her heart for kids! She enjoys family medicine because it gives her the opportunity to establish bonds with families as a whole unit and truly get to know her patients on a different level to best help them. Coming from a medically underserved community, Jenny understands how essential access to healthcare and establishing rapport with your healthcare providers are. Her special interests include pediatrics, sports medicine, women’s health, and chronic illnesses. She believes preventive medicine is the foundation of a long, healthy life and patients are their own advocates in achieving this goal. She thrives on enabling patients with the tools they need to embark on this journey.
