Dr. Marc Geissberger '91 started dental school at Pacific determined to gain as much as possible from his student experience. He served as first- and second-year class president, student body president and as a member of Delta Sigma Delta dental fraternity. Through these activities, Marc developed friendships with classmates that will last a lifetime.

"I made some of my best friends in dental school," Marc recalls. "I ran in 'Bay to Breakers' all three years with my classmates and we took some really fun trips to Napa. We've become so close that now we even take vacations together with our families."

After completing his DDS degree in 1991, Marc joined his father, Dr. Louis Geissberger '57, in his private dental practice in Greenbrae, California. Not content to simply practice dentistry, Marc also became a faculty member at Pacific shortly after graduation. Actively involved as a student leader and with a strong family history at the dental school-his grandmother and grandfather, great uncle, father and brother are all graduates-becoming a dental educator at his alma mater seemed like the perfect fit.

"I've always wanted to be a teacher," Marc says, "and I think I have been a motivator for some of my students. It probably takes them about five years after graduation to recognize that, because I'm tough-I demand a lot from them. But I have a lot of graduates come back years later and tell me that I've taught them more than they realized while they were here."

Marc's desire to inspire future dentists led to his being named chair of the Department of Restorative Dentistry in 2002. He currently teaches four days a week, conducts continuing education courses and serves as a clinical advisor during the Thursday evening clinic. His dedication to the dental school stems from the humanistic spirit he experienced as a student and the familial atmosphere he's discovered as a faculty member.

Marc Geissberger"There are excellent people here and it does feel like family," says Marc. "If it weren't for the people I work with, all the faculty and students, I wouldn't want to devote as much time as I do."

In addition to his role at the dental school, Marc and his brother, Dr. Jeff Geissberger '93, own and operate the private dentistry practice in Greenbrae that their father started in 1957. Marc is co-author of a book about aesthetic dentistry titled Aesthetic Dentistry in Clinical Practice and has lectured across the globe. He remains active in Omicron Kappa Upsilon dental honor society and serves as treasurer of the dental school's Alumni Association. He also holds the distinction as a past president of the Alumni Association.

Marc is an avid painter and occasionally teaches watercolor classes for faculty, students and staff at the dental school. He lives in Greenbrae with his wife, Christine, and three children, Justin, Robbie and Annika.
