Delphia M. Gutierrez, CAS brings Certified Addiction Specialist credentials to Chula Vista's Third Avenue corridor, providing substance-use and mental-health counseling from 1161 Third Avenue in the 91911 ZIP code. The practice's dual focus on addiction and co-occurring mental-health conditions requires medical-clearance coordination with providers such as Concentra Urgent Care for clients entering treatment with active physiological dependence. Clinical sessions address alcohol and drug dependency, relapse prevention, and codependency patterns using motivational interviewing and cognitive-behavioral interventions adapted for substance-use populations. The Third Avenue location sits within Chula Vista's downtown behavioral-health corridor, less than two miles from Sharp Chula Vista Medical Center and Scripps Mercy Hospital Chula Vista on Medical Center Drive. Addiction recovery cases involving chronic-pain management are co-treated with rehabilitation specialists at Manual Orthopedic Physical Therapy, Inc., where non-pharmacological pain protocols support clients working to maintain sobriety. Intake assessments apply the AUDIT-C for alcohol-use screening and the DAST-10 for drug-abuse severity, paired with the ASI-Lite to evaluate medical, legal, and psychosocial dimensions of each client's substance-use history.
