About the James K. and Lois Merritt Mikawa Distinguished Endowed Professorship in Clinical Psychology

The late Lois Merritt Mikawa '80 M.Ed., '87 Ed.D. established this endowed fund, through her retirement account, for the mission of enhancing ethnic and racial diversity in clinical psychology to honor her husband, 27-year Clinical Psychology Professor James K. Mikawa, Ph.D. An ethnic minority himself, James Mikawa was keenly aware of underrepresentation in clinical psychology and the importance of encouraging and supporting minority graduate and undergraduate students in the field. Established: 2006. (College of Science)
