Trey James, MD, grew up in New Cambria, Missouri, a small town in between Macon and Brookfield.  He attended Medical School at the University of Missouri and went to Internal Medicine Residency at Wake Forest University in North Carolina.  Following residency he worked as a Hospitalist at Wake Forest Baptist Medical Center then returned to Columbia in 2012 and has practiced as a Hospitalist at Boone Hospital since then.  He is currently the Medical Director of the Hospitalist Program.

Dr. James is married, with a step-son, and two boxer dogs.  He and his wife enjoy traveling to beautiful places like Colorado (and New Cambria!) and attending sports games at Mizzou.  He also likes to play Madden football on his phone if he doesn’t have anything else to do (or maybe he does have other things to do and it’s just fun).

   

Martha Herring, MD, is originally from Rochester, Minnesota.  She attended medical school at the University of Minnesota and residency at UT Southwestern.  She is passionate about providing quality patient care.  

Dr. Herring is married (to a Texan!).  In her spare time, she enjoys farming and photography.

 

Rice Petrie, MD, hails from Kansas City, Missouri (Go Royals!).  For medical school, he attended St. George’s University, followed by residency at the University of Nevada-Reno School of Medicine.  Dr. Petrie loves to be up at night, which is why he’s one of Boone Hospital’s nocturnists.  

Dr. Petrie and his wife have a five-year-old son, and they think he’s pretty awesome.  Their family is also blessed by a two year old Holland Lop rabbit, Dexter Bun Bun.  When Dr. Petrie isn’t sleeping during the day, he and his family, who are huge sports fans, love to attend Kansas City Royals, Sporting Kansas City, MIZZOU Football, and St. Louis Blues games.

   

Garrel Renick, DO, was born and grew up in Sullivan, Missouri--a rural, farming and mining community on the northern edge of the Ozarks about an hour southwest of St. Louis. He had a mostly bucolic childhood living next to his grandparents' farm, with lots of family, pets, farm animals, motorcycles, and great teachers that cared about him. He later moved to Columbia to study engineering at the University of Missouri and graduated with Bachelor of Science degrees in Electrical & Computer Engineering. He enjoyed a career in information technology before deciding to pursue his interests in medicine. Dr. Renick attended medical school at Kansas City University of Medicine and Biosciences. After graduating with his Doctor of Osteopathic Medicine degree, he completed residency training in Internal Medicine at Wellington Regional Medical Center, a community residency program in the West Palm Beach, Florida metropolitan area that is part of the Lake Erie College of Osteopathic Medicine consortium. 

Dr. Renick is board-certified in Internal Medicine. He loves caring for adults of all ages, and is proud to be a member of the talented Hospitalist team at Boone Hospital Center. His primary clinical interest is Hospital Medicine and other clinical interests include adult primary care, Integrative Medicine, and Osteopathic Manipulative Medicine (OMM). In his spare time, Dr. Renick enjoys the great outdoors, swimming, skiing, motorcycling, sailing, reading, travel, art, music, playing guitar, and computing.

 
   

Jeffrey Robinson, MD, is originally from the big city of Chattanooga, TN but came to Columbia by way of Columbus, MS.  He went to medical school at Saba University and completed residency in the Baton Rouge Internal Medicine Residency Program.  Dr. Robinson is very interested in adult medicine, and since he’s a night owl, he’s a Boone Hospital nocturnist who cares for his patients during the hours the rest of us like to be asleep.

Dr. Robinson and his wife, Ronda, have one son, Jeremy, and two cats-who-think-they-are-humans named Casper and Walker.  Dr. Robinson is a Trekkie and avid Star Wars fan who loves logging his daytime hours playing video games or other medieval fantasy games.
