Featured doctors

Rick G. Lorentz, M.D.

Always steady as a rock, there is no emergency situation that rattles Dr. Lorentz. His straight to business, no-nonsense clinical style and infamously friendly bedside manner match his abilities to keep a calm and level head during the chaos of the emergency room. With tens of thousands of hours in the ER and a background in trauma surgery, Dr. Lorentz’s vast clinical skills are a valuable asset to America’s ER.

Rob Zesut, D.O.

Dr. Zesut has been serving the local community for over ten years now. Having trained at Memorial Hermann Trauma Center in Downtown Houston he is well prepared to handle any type of emergency or urgent care condition. He has a Master Degree in Public Health and completed a fellowship in healthcare, both of which are a result of his passion for healthcare advocacy. Dr. Zesut worked with the Walt Disney Company before medical school and his experiences there to this day give him a calm and cheery disposition even in the toughest circumstances.

M. Krystina Huynh, D.O.

Dr. Krystina Huynh has been practicing emergency medicine in the Houston area since 2008. She began her higher education studies at Baylor University earning a bachelor’s degree in Biology. She went on to attend Indiana University – Purdue University at Indianapolis earning her Master of Science Degree in Biology. Dr. Huynh continued her pursuit of becoming a physician by attending Des Moines University Osteopathic Medical Center and completed her Residency in Emergency Medicine at the Medical College of Georgia. During her residency, Dr. Huynh chose her niche to be International Medicine and was able to devote her time traveling to third world countries on medical mission trips. For her, it is not just about being a physician but also about applying the knowledge and skill set to deliver quality, compassionate care. In 2011, after repeated suggestions and encouragement by both patients and staff “to open your own practice”, Dr. Huynh decided to do just that and became one of the founding members and managing partners of Priority Emergency Room-Katy. Her core vision was to provide excellent emergency care with a unique brand of service and compassion. By January 2013, she and her partners opened their second location in The Woodlands. In May 2017, Dr. Huynh and her partners sold their practice but she continues her commitment to providing emergency care in both hospital-based and free-standing emergency rooms. In addition to being a leader in the field of emergency medicine and an entrepreneur, Dr. Huynh is also a dedicated mother of two small children.

Michael Nolen, D.O.

Dr. Nolen is a native Houstonian and has been practicing emergency medicine for 19 years in both hospital and free standing emergency departments.  Dr. Nolen is a graduate of Texas A&M University and obtained his medical degree at UNT Health Science Center.  He is board certified in emergency medicine and completed his residency training with Oklahoma State University in Tulsa, Oklahoma.  His clinical training and years of experience has prepared him for any medical problem that you might have.

Christopher Valle, M.D.

Originally from Boston, Dr. Christopher Valle graduated from the University of Maryland School of Medicine back in 2001. Formerly, he was on the faculty of the Baylor College of Medicine as an attending physician at Ben Taub Hospital, gaining experience in emergency medicine at one of Houston’s two Level 1 trauma centers. Dr. Valle is no stranger to freestanding ER’s, however. He served as a medical director at two such facilities for six years. Since 2013, Dr. Valle has enjoyed volunteering as a committee member for the Houston Live Stock and Rodeo Sports Medicine division. He is also an avid runner – completing the Boston Marathon twice and as well as multiple races at both Disney World and Disneyland. He enjoys traveling and attending concerts.
