Welcome, Dr. Rivera!
SPAH is proud to welcome Dr. Jessica Rivera to our veterinary team! Dr. Rivera's journey to become a veterinarian began as a pre-teen. While visiting her grandparent's small ranch in South Texas, she witnessed the birthing of  a goat, and was moved by the weak and fragile nature of the animal. This experience ignited the beginning of a compelling desire to care for animals. Her love for animals, science, medicine, and problem solving continued to grow as she volunteered in animal hospitals, and expanded her education. Based on her Christian faith, she believes veterinary medicine is her true calling. Dr. Rivera attended Whartoun County Junior College for two years, where she was the sole recipient of a biology award for outstanding achievement. She earned a Bachelor's and Master's Degree in Biomedical Science from Texas A & M University, and graduated with her Doctor of Veterinary Medicine from Texas A & M in 2011. While attending Texas A & M University, Dr. Rivera earned recognition on the National Dean's List during her undergraduate, graduate, and professional studies. She also received a Distinguished Student Certificate from the College of Veterinary Medicine. Dr. Rivera was a team leader for a cardiovascular physiology research project under the DeBakey Research Program. Dr. Rivera was featured in the College of Veterinary Medicine Today Magazine, detailing her accomplishments.Dr. Rivera has shadowed doctors and performed volunteer and community service work in various locations while studying to become a veterinarian. She completed her requisite externships at the Texas Equine Hospital in Bryan, Tx, and at Beard Navasota Veterinary Hospital in Navasota, TX. Dr. Rivera enjoys running with her 13 year old Jack Russel Terrier Mix, Zoey, salt-water fishing, movies, and the arts. She also loves spending time with family and friends. Dr. Rivera is married to Victor Manuel Porras Jr., a Defense Attorney for Fort Bend, Montgomery and Harris Counties. Victor is also a TAMU graduate!
