Our Founder

Dr. James Caplin was a relentless force in everything he did. He devoted his life to his companies and his charitable foundation: Corpus Christi Allergy and Asthma Center, Corpus Christi Skin Surgery and Dermatology Clinic, Southwest Allergy and Asthma Foundation, Morgan Pediatric Center and Morgan Pediatric Asthma and Allergy Center. His desire to give back to the community was shown through his commitment to offer accessible patient care and participation in various charitable events both locally and abroad. Dr. Caplin entrusted his clinical practice to Dr. Alma S. Rigonan, after training her in allergy, asthma and dermatology for more than 7 years. It is our desire, as a company, to honor Dr. Caplin and continue his legacy by striving to give our patients the highest standard of care as we continue to open our doors to those who need our help.
