Meet Our Counselors

I am a Licensed Professional Counselor. I received my Master of Arts in Mental Health and Substance Abuse Counseling from St. Mary’s University in 1990 and have been licensed since 1993. Throughout the years, I have focused my practice on adults and geriatrics.  

My areas of interest include working with individuals with work injuries, chronic pain, mood disorders, trauma, self-esteem issues, and stress management. I also enjoy working with the geriatric population and have over 25 years of experience in long-term care facilities.  

During my time with Nueva Vida Behavioral Health, my areas of focus include:

  • Anxiety

  • Chronic Pain

  • Depression

  • Grief and Loss

  • Health and Medical Issues

  • Post-Traumatic Stress Disorders

  • Stress Management

  • Traumatic Brain Injuries

I love what I do and I look forward to the opportunity to walk with clients on their journey to improving their mental health and recovering from trauma. I use a client centered foundation and incorporate cognitive behavioral techniques to achieve a positive outcome.

His training included Special Operations and Guerrilla Warfare among other specialties. He served as a Military Advisor to a Colombian Counter-Guerrilla Brigade (Military) deep behind enemy lines, and later as an advisor to an Afghan Police General in Afghanistan. As a result of his personal experience, and having witnessed individuals’ and people’s effects from war, convinced him to return to school to make a difference in the lives of those who survived, but who must live on with related horrors, atrocities, and loses. Why change professions? A blend of personal
experience and education provides him a unique depth of knowledge and understanding of Post-Traumatic Stress Disorder (PTSD) among varying types of cultures and languages.

While a military member, he was also a scholar; he completed two master’s degrees and two thesis in: Justice Administration; and International Security and Civil-Military Relations. After
retiring, he worked for the U.S. army as a civilian Social Scientist conducting socio-cultural field research throughout Afghanistan for approximately four years where he gained valuable experience applying research methods and theory to real-world problems, including the effects of war on populations and resulting PTSD. He is a published author of war-related matters including: Afghanistan,

De-Evolution of Insurgency:, an article later recognized by the U.S. Department of Justice as an authoritative argument useful to their work
