Elizabeth Hogan, M.D.

Elizabeth Anne Hogan, MD

Elizabeth Hogan was born in Saginaw, Michigan but moved at only 6 weeks old. She grew up a military brat and spent most of her formative years overseas in Turkey.  She came back to the US to attend undergrade at the University of Texas at Austin.  After college, she worked as a paramedic for Austin Travis County until attending medical school at Saint George’s University Medical school in Grenada.  She knew before medical school that she wanted to be a surgeon, but it was during her first year of medical school that she discovered neuroscience and her passion for neurosurgery.  Her clinical interests include skull base surgery and she will be attending a fellowship at the University of Colorado once she graduates.  Her interests outside of neurosurgery include spending time with her husband, with family, watching movies, and traveling as much as possible.

Chase Foster

Chase Foster, MD

Chase Foster was born in small-town Texas, where he was raised by a loving mother alongside his older sister. They both instilled in him a passion for helping others, which, combined with habits built during athletics, pointed him inevitably towards medicine. He received his BS in exercise physiology from Texas A&M University before attending medical school at the Paul L. Foster (no relation, unfortunately) School of Medicine in El Paso. Neurosurgery has been to me a culmination of effort and ethos. His interests within the field are interspersed between neuro-oncology and spinal biomechanics; a marriage of the two would represent his idyllic career. In his spare time, he enjoys exercising, guitar, working outdoors, loving on his two dogs (Mia and Bean), and just existing with his beautiful wife, Haley.

Max Fleisher MD

Max Fleisher, MD


Max Fleisher was born in New York City, but he grew up in Jacksonville, FL. He attended Washington University in St. Louis for college and University of Florida for medical school. He has been interested in neuroscience since high school and had a good idea that he wanted to pursue neurosurgery even at the start of medical school. His interests within neurosurgery are still very broad at the end of intern year. His interests outside of neurosurgery are fairly narrow. They include his wife, family, restaurants, watching and playing sports, and visiting the monuments here in DC. Hayes made him jambalaya one time and he really enjoyed that too.

Hayes Patrick

Hayes Patrick, MD

Hayes Patrick is from Baton Rouge, LA, where he was raised in a beautiful family of six. He attended University of Georgia for his undergraduate career, where he graduated with highest honors in Biology and Neuroscience, received a certificate in Personal and Organizational Leadership, and was invited to speak at Spring Commencement. He briefly returned home to Louisiana to attend medical school at LSU Health Sciences Center in New Orleans, where he developed a passion for neurosurgery. His interests within the field of neurosurgery include Neuro-Oncology, Vascular, organized neurosurgery and public health. His interests outside of residency include family, friends, movies, running/hiking around DC, traveling and introducing his co-resident to Cajun food. He also thinks that Max makes some pretty decent tacos in return.
