Currently, he is Assistant Clinical Professor, University of California San Francisco School of Dentistry, Department of Orofacial Sciences and has served as Associate Clinical Professor at the University of the Pacific College of Dentistry.

Dr. Merijohn earned his dental degree, summa cum laude, in 1979 from the University of Illinois College of Dentistry and received his certificate in periodontics in 1981 from the University of Washington.
