“Of all my teaching that I have done over the years both inside and outside of the OC District Attorney’s Office, I find my experiences at Chapman to be the most rewarding because of the caliber of the faculty, administrative staff and students I have had the pleasure of meeting. The faculty and administrative staff are professional, dedicated and enthusiastic. The support and training that is given to the students is exceptional.
