Bachelor of Science, Cal Poly SLO

Denise grew up in Santa Cruz and earned a BS from Cal Poly in San Luis Obispo. She has been with ADI since 1991 as both a counselor and administrator experienced with DUI, Drug Diversion, Domestic Violence and Outpatient Treatment. She describes her ADI experience as follows: "My position is a blend of interacting with the clients and coordinating our compassionate and talented staff. No two days are ever alike; I am most grateful for the chance to guide our clients through the DUI process, and witness many life altering behavior changes as people progress through our program. The smiles, the thanks and the positive feedback upon program completion is awesome to witness! The addition of our new Outpatient Treatment Program and Anger Management Program will allow us to provide much requested additional services to the local community."
