The Physician Team at ER of Dallas
Frankford Road runs on a deep bench. Nine board-certified physicians rotate through this emergency room, spanning surgery, critical care, internal medicine, and family practice, so the range of what walks through the door is matched by the range of who is here to meet it.
One Roster, Many Specialties
A freestanding ER cannot choose its cases. Our Dallas physicians bring training from general surgery, otolaryngology, thoracic surgery, internal medicine, and critical care into a single team, which means a complex abdomen, an airway problem, and a decompensating chronic condition each meet a doctor whose background fits the problem.

Every physician listed below is board-certified and treats patients at our Frankford Road emergency room.
Dr. Adetunji Adesanoye, MD
Serves: ER of Dallas
Dr. Adetunji Adesanoye is a board-certified family medicine physician with more than three decades of experience caring for patients across every stage of life.

Dr. Zahoor Ahmed, MD
Serves: ER of Dallas
Few physicians come to emergency medicine with the breadth of training Dr. Zahoor Ahmed brings to it. A graduate of Liaquat National Medical College, he completed advanced residency training in thoracic surgery and family medicine before centering his practice on emergency care.
His published work spans surgical and pulmonary topics, and that research background shapes how he approaches chest pain, abdominal emergencies, and the layered internal medicine presentations that often arrive without warning.
With more than five decades in practice, Dr. Zahoor treats patients at ER of Dallas, with the experienced judgment that emergencies demand.
Dr. Alfonso Cardenas, MD
Serves: ER of Dallas
It is unusual to find an emergency physician whose training also runs through general surgery and head-and-neck surgery, but Dr. Alfonso Cardenas built that uncommon foundation early. He earned his medical degree from the David Geffen School of Medicine at UCLA and completed his emergency medicine residency at Kern Medical Center, with additional residency work in surgery and otolaryngology.
Across more than four decades of emergency medicine practice, that surgical fluency has shaped how he reads acute abdominal pain, airway emergencies, and trauma cases that arrive with multiple injuries. He treats patients at our Mesquite Beltline and Dallas locations.
Dr. Trisha L. Dipprey, MD
Serves: ER of Dallas
Dr. Trisha Dipprey has built her career at the intersection of three demanding specialties: internal medicine, critical care, and emergency medicine. She earned her medical degree from the University of Texas Medical Branch at Galveston in 1995 and trained in internal medicine before adding critical care and emergency practice to her clinical portfolio.
That triple grounding shapes her approach to the most clinically complex patients in a freestanding ER, particularly those with post-surgical complications, multi-system illness, or rapidly evolving conditions that demand fast stabilization before transfer. Dr. Dipprey serves patients at ER of Dallas.
Dr. Tushar Garg, DO
Serves: ER of Dallas
Dr. Tushar Garg is a board-certified family medicine physician dedicated to delivering responsive, hospital-level care in a freestanding emergency setting.
He earned his medical degree from the TCU and UNTHSC School of Medicine and has built clinical expertise in the management of stroke, cardiovascular emergencies, and the spectrum of urgent illnesses and injuries that present to the emergency department.
Dr. Garg serves patients at ER of Dallas, working alongside a team committed to short wait times and personalized care.
Dr. Christopher Litchfield
Serves: ER of Dallas
Dr. Christopher Litchfield combines a decade of full-time emergency medicine practice with leadership in two adjacent fields: hospital medicine and digital health.
He completed his medical degree at the Universidad Autonoma de Guadalajara and his family medicine residency at the University of Texas Health Science Center at San Antonio, and is board-certified in family medicine.
He founded a Texas telehealth practice and is an active member of the American Society of Addiction Medicine, working at the intersection of urgent and longitudinal care. He treats patients at ER of Dallas.
Dr. Irfan Rafiq Rana, MD
Serves: ER of Dallas
Dr. Irfan Rana practices at the meeting point of internal medicine, family medicine, and emergency care, a combination that suits the wide variety of patients arriving at a freestanding ER without an appointment.
He earned his medical degree from Baqai Medical College in 2000 and has built more than two decades of clinical experience across hospital-based and outpatient settings. His emergency work covers the careful management of patients with chronic disease who present in crisis, along with the everyday case mix of acute infections, urinary complaints, and dehydration. He treats patients at our Dallas and Plano emergency rooms.
Dr. Talal Zahoor
Serves: ER of Dallas
Dr. Talal Zahoor has built his career across two parallel tracks: bedside emergency medicine and the operational side of running emergency and urgent care facilities.
He earned his medical degree from the University of Queensland Medical School in 2014 and has since practiced as both an emergency medicine physician and a hospitalist, with peer-reviewed publications spanning surgical, internal medicine, and emergency topics.
His work as a healthcare entrepreneur has focused on expanding access to community-based emergency and urgent care. He treats patients across all of our North Texas locations.
Dr. Tariq Vora
Serves: ER of Dallas
As Regional Medical Director for our emergency care network, Dr. Tariq Vora oversees clinical operations and physician integration across multiple North Texas locations.
