Dr. Chase Cates, DO, MPH, AAHIVS
Medical Director Physician – LGBTQ Healthcare, HIV, Internal Medicine
Dr. Chase Cates grew up as a closeted kid in Dallas, TX. Seeing the consistent discrimination of LGBTQ people faced kept him in the closet until medical school.
He obtained a bachelor’s degree in biology from San Angelo, TX, and a Masters Degree in Public Health in College Station. TX. He studied in Lake Erie College of Osteopathic Medicine at Seton Hill for medical school, and completed his clinical rotations in Elmira, NY. During this time, he was on an away rotation at an HIV clinic in Dallas that ignited his passion to help this demographic. After finishing medical school, he did his residency in Internal Medicine in Searcy, AR.
While in Arkansas, he witnesses the discrimination LGBTQ people face in healthcare firsthand. He experienced hate for being engaged to his partner. He had nurses make comments behind his back. He was at his limits with these abuses and did what he could and educated my peers around him. He presented several lectures regarding LGBTQ health issues, so others were aware of what people faced. This led him to be the first to complete a fellowship in LGBTQ Healthcare and HIV at University of California at Los Angeles (UCLA). He is prepared to take what he has learned to provide care for his community in the south, where he feels it is desperately needed. He is proud and excited to be joining AARC in providing that care.
Dr. Manuel Endo Carvajal, MD
Physician, Infectious Diseases
Dr, Endo was awarded his Doctorate in Medicine from Universidad Libre in Cali, Colombia. He did his social service training transferring critically ill patients from isolated communities in the Colombian pacific coast to high-complexity medical centers located in the most important cities of Colombia. Subsequently, he completed his Residency in Internal Medicine and Fellowship in Infectious Diseases at the University of Texas Health Science Center in San Antonio, Texas.
Dr. Endo has a special interest in the prevention and treatment of metabolic diseases of patients living with HIV, gender-affirming therapy, and penicillin allergy. Dr. Endo is a very physically active physician; he enjoys playing competitive soccer and working out at the gym as he believes doctors should be role models of cardiovascular fitness for patients.
