Clinical Specialists


Diana Vo, LMFT

Diana is a licensed marriage and family therapist who has been in the field of mental health for over 10 years. She earned her bachelor’s degree at the University of California Santa Barbara and her master’s degree at Alliant International University. Her background includes a variety of settings including inpatient hospitalization, residential treatment, partial hospitalization, intensive outpatient, community mental health treatment and private practice. Diana came into the substance abuse arena by chance but has since developed a deep appreciation for 12 step programs and a compassionate understanding of the recovery process. Rather than seeing addiction as a moral failing, she views it as a trauma response and as such, is able to frame her treatment approach in a way that empowers her clients rather than shames them.

As the clinical director, Diana is responsible for the oversight, development and implementation of the clinical functions of Renaissance Recovery by offering leadership, supervision and support in accordance to state and federal regulations. She also gets to encourage the development of Renaissance Recovery’s pre-licensed clinicians as well as the growth of her clients.

Dave Orecchia


David began his journey into a new life through a treatment center in Arizona and then onto Huntington Beach, California by way of New York.

David graduated in August of 2019 with a Master’s Degree in Marriage and Family Therapy and is currently an Associate Marriage and Family Therapist with Renaissance Recovery.

Before working at Renaissance Recovery, David worked at both private and community based substance abuse treatment centers, helping round out his skills as a clinician. David views these two different experiences in helping to shape his role as a therapist focused on improving the life of an individual through sobriety. David’s own experience in sobriety has helped provide perspective on the trials and tribulations of moving into a much healthier lifestyle centered on one’s own passions and interests in life.

David operates from a Bowen theory of family therapy, which is focused on the intergenerational transmission of traits and characteristics. David likes to conduct individual and group therapy sessions through the exploration of past life events and the ways that these situations have led to an individual’s current behavior and functioning relative to substance abuse. David hopes that his spiritual experience in sobriety, interest with psychology, and training as a clinician can help lead others to a worthwhile experience of their own in recovery.
