Clement Yeh, MD

Dr. Clement Yeh

Dr. Clement YehDr. Clement Yeh has had the blessing of being a lifelong Texas resident. He was born in Dallas and attended Arlington Martin High School. He then attended Baylor University on a Presidential and Premedical scholarship, where he obtained a degree in biology and a minor in chemistry. In addition to being a member of Sigma Alpha Epsilon fraternity, he was also a 4-year starter on the Baylor men's soccer team and named the team's most valuable player his senior year.

Dr. Yeh attended Texas Tech University School of Medicine for his medical education. During this time, he completed his clinical clerkships in El Paso, where he mentored University of Texas at El Paso premedical students in guiding their career choices. This is also where his love of Mexican food was born.

Later, Dr. Yeh continued his medical education at Parkland Memorial Hospital and UT Southwestern Medical Center in Dallas, where he completed a residency in anesthesiology. While a resident, he published research in cardiovascular anesthesia and presented research posters at national anesthesiology meetings.

Although Dr. Yeh thoroughly enjoyed the fast-paced and intellectually stimulating environment that anesthesiology provided, his desire for a more traditional patient-physician relationship spurred him to pursue additional training in the field of pain medicine.

Dr. Yeh remained at UT Southwestern Medical Center to complete his fellowship training in interventional pain management, where he was trained in the latest interventional techniques and treatments for acute and chronic pain conditions. He also learned the importance of using a multidisciplinary-guided approach to treating pain. During this time, Dr. Yeh presented cutting-edge research findings at national pain society meetings.

When not seeing patients in the clinic or practicing anesthesiology part-time, Dr. Yeh can be found playing ultimate Frisbee and soccer at Zilker Park, as well as wakeboarding and snowboarding when the seasons permit. Although he has spent the majority of his life in the Dallas area, he is now pleased to call our state’s wonderful capital home.

Mahan Ostadian, DO

Dr. Mahan Ostadian

Dr. Mahan OstadianDr. Mahan Ostadian considers himself a Texas native since his early college years. He attended the University of Texas in Austin, where he completed his premedical training and obtained a degree in biology. During this time, he remained active in the community while volunteering in the emergency room at Round Rock Community Hospital. He also continued his goal of becoming a physician by staying involved in Alpha Epsilon Delta pre-medical honor society at the university.

Dr. Ostadian left Austin to attend University of North Texas Health Sciences Center - Texas College of Osteopathic Medicine in Fort Worth to complete his medical degree. While obtaining a solid foundation in the basic sciences, he also learned the interrelationship of the body's nerves, muscles, bones, and organs, as well as the importance of treating the whole person. He was selected to the Dean’s List for academic excellence during this time.

Next, Dr. Ostadian continued his medical training by completing a residency in anesthesiology at Scott and White Memorial Hospital. After his residency, Dr. Ostadian remained on staff as an assistant professor of anesthesiology and was heavily involved in helping treat patients’ post-operative pain. Currently, he enjoys his continued involvement at Scott and White in resident education.

While working as faculty at Scott and White Memorial Hospital, Dr. Ostadian decided to pursue fellowship training in interventional pain management at the respected UT Southwestern School of Medicine and Parkland Memorial Hospital in Dallas.

During his fellowship training, Dr. Ostadian was involved in several research projects and presented research posters at national pain management conferences. He is double-board certified in both anesthesiology and pain management by the American Board of Anesthesiology.

Dr. Ostadian was thrilled about returning to Austin with his wife Mona and their daughter Alana. He is a huge college football fan and hopes his daughter will someday have the same passion that he has for Longhorn football. He is also excited to join with Dr. Yeh, who shares his goals of providing exceptional, compassionate care to all of their patients.

James Fay, MD

Dr. James Fay

Dr. James Fay is the latest addition to the provider staff of Republic Spine and Pain.  A native Texan, Dr. Fay was born at Fort Sam Houston in San Antonio, and then traveled the country as the proud son of an Army Dental Corps officer.  Dr. Fay attended Robinson Secondary School in Fairfax, Virginia, and then earned his Bachelor of Science degree in Electrical Engineering from Rose-Hulman Institute of Technology in Terre Haute, Indiana, a college recognized for its #1 undergraduate level engineering education in the nation.  He is also fluent in German and earned his Technical Translator’s Certificate after completing a year at the University of Stuttgart in Germany. 

Dr. Fay’s path to medicine led him back to Texas to pursue a Master of Engineering degree in Bioengineering at Texas A&M University.  He completed a graduate level project on the biomechanical stresses produced in the knee.  After working at UT Southwestern in Dallas for two years in pulmonary research, Dr. Fay followed his passion for aerospace to the Johnson Space Center in Houston.  Dr. Fay worked for NASA and helped design biomedical sensors to be used on the International Space Station. 

Realizing that his life’s passion was to engineer the human body, Dr. Fay entered medical school at the Texas Tech University Health Sciences Center. He completed his clinical rotations in El Paso, and received his Doctor of Medicine degree in 2005.  Combining his love of engineering and medicine, Dr. Fay completed residency in anesthesiology at the University of Texas Medical Branch in Galveston in 2009. 

After residency, Dr. Fay returned to Lubbock and worked as a staff anesthesiologist for NorthStar Anesthesia, and served as the Chief of the Anesthesia section at Covenant Medical Center.  Dr. Fay specialized in pediatric and neuroanesthesia, as well as regional anesthesia for orthopedic procedures.  After six years in private practice anesthesia, Dr. Fay realized he missed the ability to follow-up with his patients on a long-term basis, and answered the calling to pain medicine.  He completed an interventional pain medicine fellowship at the University of Texas Medical Branch in Galveston. 

Dr. Fay is relocating to the Austin area after practicing pain management in Lubbock.  He specializes in multi-modal treatment of pain, to include injection therapy, spinal cord stimulation, kyphoplasty for vertebral compression fractures, medication management, and implementation of physical therapy.  Dr. Fay is triple board certified by the American Board of Anesthesiology in Anesthesiology, Pediatric Anesthesiology, and Pain Medicine. 

Dr. Fay, his wife, Lisa, and their three children, Caroline, Lorelei, and Patrick, are looking forward to calling Georgetown home.  In his free time, Dr. Fay enjoys running (he has completed 12 full marathons and multiple half marathons, to include the Austin Marathon), traveling (he never misses an Aggie football game), and grilling.  He is a member of the American Society of Anesthesiologists, the Texas Medical Association, and serves as a Delegate for the Texas Society of Anesthesiologists.
