Our Team

David Longridge

President / Founder

Dave Longridge is the President & CEO of Balboa Horizons Recovery Services, which he founded 14 years ago. With fully-licensed inpatient facilities and outpatient programs in Newport Beach and Costa Mesa, Balboa is Joint Commission accredited to provide treatment programs to those suffering from alcohol and drug addiction, as well as those who have co-occurring mental health conditions.

Located in coastal Orange County, Balboa Horizons offers the full continuum of addiction recovery programs for men and women. Its specialized, comprehensive recovery programs provides a valuable continuity of care for clients, their families, referring professionals and hospitals. Balboa Horizons’ programs are designed with the end goal in mind – providing a customized treatment process that fosters maximum progress and growth. The organization has a sterling reputation in the treatment industry for excellence, standard of care, and positive recovery outcomes. In addition to serving young adults and being a top choice with primary treatment centers, interventionists, therapists, and other professionals, Balboa Horizons is also aligned with the Employee Assistance Programs of some of the largest unions in the country, particularly those serving the transportation industry – on land or air. Balboa Horizons has also received The Joint Commission’s Gold Seal of Approval for Behavioral Health Care Accreditation, the highest ranking for standard of care any addiction treatment organization can achieve.

Dave honed his executive management skills in the auto industry, and – grateful for his own recovery from alcohol addiction 21 years ago, began “giving back” by originally helping those struggling with addiction, later financing an addiction treatment center, then applying his management talents to running Balboa Horizons.

In addition to supporting the recovery community, Dave has been involved with the Orange County homeless shelter, United Way, the Special Olympics, and providing planning and management consultation services to other small business owners.

Her publications brought her to the attention of a House Sub-committee who was investigating the harmful effects of psychiatric medications on children as it follows them into adulthood.

Wesley Geer

Director of Rock to Recovery

Wes has been a professional musician for over 20 years. He first found success as the founding member of Jive Records artist Hed P.E. as guitarist, songwriter and producer. After touring the world for eight years, Wes left the band for a lifestyle change and ultimately landed in rehab. Then in 2010, at almost three years sober, he was approached to play with the legendary band Korn. He joined Korn and worked with them as their touring guitarist for the next several years, traveling to 42 countries, headlining shows, playing to crowds of 80,000 people, and appearing on a number of recordings and cable and TV shows.

Wes’s music has been featured in many feature films, video games, radio, and television shows. He has also long had a passion for teaching music. Previously a music teacher at The Fusion Academy’s Huntington Beach campus, Wes now directs Balboa Horizons’s Rock to Recovery program.

Wes believes an essential piece of recovery is walking through the discomfort of sober feelings—challenging oneself through personal growth.  By learning to create deeper connections with others, we ultimately find new ways of feeling “high” through life experiences. In playing music together, these elements coalesce organically, providing an uplifting and transformative experience.
