He then entered the University of Florida College of Medicine. While in medical school, Dr.Joshi received many honors. The one that he is most proud of is the Student Hippocratic award given by the medical students to “a classmate who represents honor, dignity, and a genuine passion for all those seeking medical care.” Dr. Joshi served as his medical school class president from 1995-1998, and was bestowed with the honor of giving the student address at graduation. During the ceremony, his classmates presented him with a special one-time award, The Most Valuable Person Award. This recognized his significant contribution to education, advancement of student issues, and his desire to help the class become successful. That day, May 23rd 1998, remains one of his most memorable.

After graduating from medical school, Dr. Joshi attended the Mayo Clinic Internal Medicine Residency Training program in Jacksonville . He completed his residency in 2001 and served as chief resident in 2001-02.
