About Dr. Bartholomew: “I enjoy my field because many of the patients I treat have disorders that are not well known to other physicians. In that way, patients are extremely thankful that there are physicians that deal with these unusual and often complicated diseases. Many of our patients go from doctor to doctor before they find the right answer to their medical problems, and it is gratifying to let them know that someone understands what is wrong with them. In addition, I like the opportunity to use the newer anticoagulants to treat patients who have blood clots and to help advance the field of medicine related to those events.”

Leisure Activities: In his spare time, Dr. Bartholomew enjoys fishing, hiking, skiing, writing and reading.
