Clinical Faculty Appointments

William Fell, M.D.
Dr. William Fell completed his Ear, Nose & Throat specialty training in 1997, having trained at Parkland Hospital in Dallas, Texas from 1991-1997.  He grew up in Anchorage, Alaska, attended college at The University of California, Santa Barbara and medical school at Oregon Health Science University in Portland.  Since completing his residency training, Dr. Fell and his family have traveled and practiced in Wyoming, Alaska, Guam and Delaware.

Dr. Fell’s travels, different work environments and patient experiences have allowed him to develop knowledge, experience and a multitude of different subspecialties in the field of ear, nose and throat.  Not all ENT problems have a simple solution.  Dr. Fell has extensive experience performing surgery for chronic ear disease including cholesteatoma, and he is skilled in complex and revision sinus surgery.  Dr. Fell also has a great deal of experience providing surgical treatment for head and neck tumors and cancer.   

Stan Potocki, M.D.
Dr. Potocki graduated from Baylor University in 1990.  He received his medical degree from Texas Tech University Health Sciences Center in 1994.  After completing his Otolaryngology Residency, he and his family moved to Lubbock.  Dr. Potocki chose the Ear, Nose and Throat specialty early in his training.  He quickly became interested in the complexity of the anatomy and function of that part of the body.  He finds the variety of ENT practice to be very satisfying, including the ability to help people of all ages.  Quickly relieving a child’s ear infection with tubes, or lessening sore throats by tonsillectomy is rewarding.  Improving quality of life for patients by helping with voice disorders, dizziness and sinusitis also makes his work enriching.  Dr. Potocki has been excited to incorporate recent advances in sinus surgery by adding balloon sinuplasty to his practice.  This has allowed more patients to be treated in the office with less discomfort and a shorter recovery period compared with other sinus surgery techniques that require general anesthesia.
