Tina is highly recognized among her colleagues in the field of treatment for substance use disorders, a field she has worked in since 1995. She holds a Bachelor’s Degree in Human Services Management from Phoenix University; and a Licensed Advanced Alcohol and Drug Counselor LAADC credential from California Consortium of Addiction Programs and Professionals (CCAPP). She was recently selected as a Surveyor for CARF, the Commission for Accreditation of Rehabilitation Facilities – a quest she will begin in 2019. Tina is very active in the community. She is a member of CCAPP; San Bernardino County’s Association of Community Based Organizations (ACBO); and the Upland-Foothill Kiwanis service organization. She began her tenure at IVRS in administration as executive assistant back in March 2006. She quickly proved herself and was promoted into program management. She has supervised both residential and outpatient programs, including New House, Inc. during IVRS’ attempted merger back in 2011. Tina is a go-to gal. In addition to her program management duties she also served as quality assurance coordinator and liaison to IVRS’ IT contractor – coordinating all aspects of technology installs and repairs. She also served as Director of Operations before being promoted to Chief Executive Officer. As a result of many years of hands-on experience, Tina is a seasoned professional. She is a profound leader, with a vast array of positive qualities and character, which are integral components for maintaining a high level of client care for individuals suffering from substance use disorders. On a personal note she is married to her best friend, and loves her family and her  5 grandchildren.  Riding her motorcycle is her absolute favorite thing to do.
