About

A native of Southern California, becoming a nurse midwife was a childhood dream for Denise — which evolved later with her own personal health experiences, childbirth, and included family members’ health experiences as well.

She considers it a privilege to provide health services to all women. Denise describes herself as an excellent listener and believes communication is one of the key elements to a great provider/patient relationship. She feels that every patient deserves the gift of time incorporated with top quality health care. She enjoys teaching and is very patient.

When not working, Denise enjoys reading and spending time with her grandchildren. She likes trying new restaurants with her four grown children. Denise has a rescue dog who she admits is very spoiled.
