Dan Osborne

Dan is proud to be a living example of Gilead’s broad opportunities for advancement. He began his career at Gilead as a per-diem employee in 2001, was then promoted to a variety of clinical and administrative roles, and took on the role of Chief Executive Officer in December 2013.

Dan is passionate about serving the needs of individuals with severe psychiatric disabilities. He has committed his career to making sure that their voices are heard, and that they are empowered to reach for their dreams. Dan has experienced firsthand the powerful process by which Gilead adds value to both the individuals who are receiving services and to those who live and work within the communities where Gilead operates. Social justice, human rights, compassion and quality care are important values that Dan stresses to all Gilead employees. He continues to fight for these values despite the daily challenges.

Throughout his career, Dan has also remained active at his local church and has devoted his time to the middle school youth program. For Dan, faith and human services go hand in hand. Spending family time with his wife and two daughters, keeping up with the local sports teams, participating in local road races, kayaking and bass fishing on local ponds are what gives Dan joy outside of Gilead.

Justin Salvio

Beginning at Gilead in 2002 as a Program Director Justin has enjoyed the opportunity to develop creative interventions, inspire staff, and help them grow to be effective and compassionate leaders and caregivers. With over thirty years serving youth and adults in residential, outpatient, partial hospital, mental health and substance abuse treatment, Justin has a unique approach and deep commitment to recovery and well being that is grounded in fostering the individual’s innate ability for healing through facilitating a deeper sense of self and connection to others.

With a B.A. in Religious Studies from Yale University, his work at Gilead feels like a vocational direction with a slice of spirituality. Justin brings a wealth of healing experiences to his current position as Chief Operating Officer, including an 18-month journey to Japan to study martial and healing arts, and becoming certified in Rubenfeld Synergy Method (an alternative healing modality that integrates touch and talk therapies).

Meaningful relationships are very important to Justin, which has led him to meet with a group of 7 male friends for the over 20 years to explore the depth of relationships and personal growth. Justin has a love of family, food, cooking, swimming, sailing, and acting. Before grilling vegetables seasoned from his garden, he and his dog Chloe can be seen walking at the nearby lake.
