In 1995, Evan Chen, a member of Theta Chapter at Stanford University, was diagnosed with leukemia. Their chapter, along with Evan’s friends, organized a joint effort to find a bone marrow donor. What resulted was the largest bone marrow typing drive in the history of the NMDP and Asian American Donor Program (AADP). In a matter of days, over two thousand people were typed. A match was eventually found for Evan, but unfortunately by that time the disease had taken its toll on him and he passed away in 1996. In Evan’s memory, the national philanthropy for Lambda Phi Epsilon was established and the fraternity has been working with the organization from that point on.
