Who We Are


Our Vision

Founded in 2012, The Haven at College works to help college students with mental health and substance use challenges thrive in school and life. Today’s students face unprecedented challenges and unique pressures, yet few college-focused treatment options exist for them.

We believe students should be able to work through, heal from and overcome these issues while also enjoying a vibrant collegiate experience. Students who complete The Haven programs have a 94% graduation rate, much higher than the 63% national average. 

We work in an independent, customized way with our university partners. This makes it possible for us to provide programming that compliments existing services to provide for students who need specialized or heightened levels of care. Students appreciate our ability to confidentially meet their unique needs. 

We’ve been accredited by The Joint Commission, an independent, non-profit organization that accredits over 20,000 healthcare facilities in the United States. Joint Commission accreditation is recognized nationwide as a symbol of quality. We’re also a member of the Hazelden Betty Ford Patient Care Network, an invitation-only collaboration between pioneering addiction treatment and recovery services organizations nationwide.

Meet the Team


Sharon Weber and Holly Sherman


The Haven at College Co-Founders Holly Sherman and Sharon Weber got sober together in 2005 at a West LA sober living facility. They forged a lifelong friendship and a shared dedication to helping others find recovery. As a result of their experience working with younger residents in the sober living community, they discovered an unmet need for supporting college students. In 2012, they founded The Haven at College, in collaboration with University of Southern California.

Sharon’s previous consumer products and brand strategy career with Fortune 500 companies like Nestle, Unilever, Kellogg’s and Warner Lambert provided the ideal background to formulate The Haven’s brand position and strategic direction. Holly was able to leverage her training as an attorney and her work with non-profits dedicated to assisting at-risk youth to support The Haven mission. They both are at home on university campuses after receiving multiple degrees in higher ed — Sharon with a B.A. in Liberal Studies from University of the Pacific and an MBA from California State University, Sacramento, and Holly with a B.A. from Vassar College and law degrees from The London School of Economics and The University of Texas.

When not at The Haven working with students, parents or the university administrators, Holly enjoys surfing, ocean swimming and “wet-sand cycling” at the shoreline. Sharon is an avid golfer and hiker and is passionate about spending quality time with family and friends. Both Holly and Sharon enjoy traveling and have attended recovery meetings in cities around the world including New York, London, Sydney, Prague and Amsterdam.
