You may contact any member of Gilead’s administrative leadership team via phone or email on our may Contact Us page.

Dan Osborne

Dan is proud to be a living example of Gilead’s broad opportunities for advancement. He began his 13-year career at Gilead as a “per diem” employee, was then promoted to a variety of clinical and administrative roles, and recently 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, 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, playing with Sadie (his 13 year old dog), keeping up with the local sports teams, participating in local road races, and an occasional search for a rare football card 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 almost 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 past 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.

Lucy McMillan

In 2018 Lucy became Gilead’s Chief Development Officer. She joined the Gilead Team as the Director of Development and Public Education in 2005. Lucy had heard about Gilead for years from her father who was very committed to our mission to improve the lives of individuals living with mental illness.

Before earning her MPH from Columbia University, Lucy worked in the nonprofit sector as a mental health worker, a clinical case manager, the director of a family shelter and transitional living program and the director of marketing and community relations for a nonprofit affordable housing developer.

Lucy’s love of people, parties, dance and music came together when she produced and managed, Midnight on Main, a New Year’s Eve celebration for the city of Middletown in 2011 and 2012. Her personal involvement and commitment to community development efforts are demonstrated by her involvement on several nonprofit boards and her United States Peace Corps Volunteer work in Togo, West Africa.

Betsy Gerich

Betsy’s passion for helping people in recovery from mental illnesses stems from having grown up with a brother who suffered from schizophrenia. She has often wished that a continuum of services such as Gilead now offers had been available for her brother in the 1970’s and 1980’s.  Although the mental health system has come a long way, there is further collaboration to be done with those in recovery and their families, significant others and friends. Betsy feels privileged to be a small part of that overall change.

Betsy graduated from Yale in 1984, with a Bachelor’s degree in Chemistry, and worked in oncology labs for the first several years after college.  She then returned to Southern CT State University, earning a Master’s degree in Counseling in 1989.  For the past 30 years, she has worked for non-profit mental health services, including being on one of the first Assertive Community Treatment teams in the state for over 13 years.  For the last 15 years, Betsy has held a variety of positions at Gilead, including Program Director at ACT and Manager at SCAP. The majority of her time – 12 years – has been spent as SCAP Program Director. In her current position as Clinical Director of Residential Programs, Betsy continues to work tirelessly to improve the quality of life for all Gilead clients.

In her spare time, Betsy is an avid reader and walker; she tries to do both of these activities every day.  In addition, Betsy is a lover of all things feline and has one very spoiled cat!

Joanne Tan

Joanne has been working in the mental health field for 16 years. A graduate of Bay Path University with a Bachelors in Psychology and a concentration in Gerontology, she went on to Springfield College where she obtained her Masters in Social Work in the Advanced Generalist Program. Right after graduation, she started working as a Crisis Clinician and Outreach Clinician in Springfield, MA. Rising within the ranks at her previous company, she has been in various positions as Quality Assurance Associate, Clinical Supervisor, and MA State Clinical Director.

Joining the Gilead team in March 2018 as Clinical Director of Community Services, Joanne hopes that her experience in the clinical field can help enrich the wonderful work that Gilead does. She believes in giving back to the community and was a frequent volunteer, head cook, and sat on the board of Enfield Loaves and Fishes for the past 11 years. When not working or involved in volunteer activities, Joanne enjoys spending time with her husband, two senior rescue dogs, reading, traveling, learning about new cultures, and dining around!

Linda Walsh

For over 30 years Linda has dedicated her professional life to helping people overcome adversity. Linda believes in recovery and that individuals with serious mental health issues can learn skills that enable them to live the life they choose.

Linda values the simple human connection because she feels that shared experiences are powerful ways to provide hope and strength. Her experience includes working in a state hospital, being as a case manager in one of the CT’s first community-based mental health programs and then helping that organization grow in response to the deinstitutionalization movement.

As the Director of Contracts and Licensing she ensures that Gilead meets its responsibility to provide a healthy, skilled, efficient organization. Nicknamed “Selkie” by her husband, Linda will spend hours in the water while at the beach. On Halloween Linda’s house gets turned into the “Tunnel of Terror”, a neighborhood classic that many fear to enter. She loves reading, biking, hiking, listening to live music, traveling with her family and using the fresh herbs from her garden to cook up a flavorful meal.

Daniel Millstein

Dan joined Farrell Treatment Center in 2006. He came to Farrell with clinical experience in all phases of substance abuse treatment, including detox, outpatient, intensive outpatient and residential treatment. Dan became the Clinical Director of Addiction Services in 2020.

For Dan, helping people with addictions is a calling, not a job. Dan began counseling people as an attorney in 1980. After years of assisting people navigate the legal system while dealing with personal crisis, it became clear to him that he was getting involved too late to address the cause of the problem. Dan earned his master in social work from Fordham University and went on to become a Licensed Clinical Social worker. As someone personally effected by substance abuse, the opportunity to help people suffering with this disease has been an incredible opportunity.

Dan is sustained by his wonderful family consisting of his wife, his five daughters, their significant others, and his six amazing grandchildren. Dan is most at peace in the wilderness with his black lab, Ozzie.

Joe Mascolo

Joe joined the Gilead team in 2005 as our Systems Administrator. He was promoted to the role of Director of Information Technology in 2007. In this role he set up the IT department, which is now comprised of a team of four.

Volunteering in high-energy fundraisers, seeing clients grow and flourish, and above all, working with wonderful people who care about what they do has made this one of Joe’s most rewarding positions.

Joe is passionate about camping, hanging out with good friends and playing video games. He briefly left Gilead in 2013 but returned because he “believes in Gilead’s mission and “missed being in an environment which allows employees and clients to thrive.” Joe’s infectious laugh, which can be heard from building to building, combined with his sense of humor and IT knowledge has allowed him to bring new and innovative technology to Gilead, making our agency a leader in service delivery and quality.

Sheryl Schieffer

Sheryl earned her Master’s Degree in Industrial/Organizational Psychology from the University of New Haven. Having interned at nonprofit agencies, Gilead’s welcoming community was a natural transition for her. She joined the Human Resources team in 2011 and held several positions within the department before becoming the Director of Human Resources in 2018.

Sheryl is on the Board of Human Resources Young Professionals Group and is a member of the HRACC. She enjoys volunteering on various committees, both for Gilead and in the community. In her spare time, you will find her at a Zumba class or trying foods from different cultures.

Rob Snyder

Rob came to Gilead in 1994 thinking he would gain some hands on experience and move on. He quickly realized he really wanted to stay because “Gilead is something special”. Starting as a Program Manager, Rob found his passion in analyzing the great work done on a daily basis at Gilead. As a Licensed Clinical Social Worker with a love for technology, Rob brings a unique set of skills to his current position as Director of Quality Assurance. During his 21 year tenure Rob created a systematic infrastructure that allows Gilead to analyze the work we do, demonstrate our successes, and examine areas that need improvement.

Helping others to have a better life and navigate things they might not have the knowledge or skills to navigate on their own led him to nonprofit work. Rob is very proud to work at Gilead, which is demonstrated by his participation in all aspects of the work. He rarely misses a Gilead event, especially if chocolate is on the menu.

He enjoys spending time with his wife and two girls. They often go hiking, and kayaking, and are sure to make an annual camping trip to Acadia National Park, one of Rob’s favorite places. Protecting the environment is a priority for Rob, which led to his investment in solar panels for his home and an electric car for his family. Up for any challenge Rob has been seen sky diving, bungee jumping, driving a motorcycle across the United States and backpacking through Europe.

David Ferrigno

Dave joined the Gilead team in 2018 as the Facilities Manager and was promoted to Director of Facilities in 2019. He joined Gilead in an effort to give back and find a place where he felt he could help make other’s lives a little better. In his role, he has over site of the properties owned and leased by Gilead. With his team, they work to keep properties safe, stable and effective for all clients and staff.

Dave enjoys spending time with his family, working with his hands, all sports (football in particular), and watching movies.

Leila Linntoya Jarrett

In January 2020 Linntoya returned to Gilead as Clinical Department Director after a four-year hiatus at another agency. It was an easy decision for her to return to Gilead because of the relationships in the agency and the consistent and wonderful work being done by the employees at Gilead.

Linntoya earned her Ph.D. in Marriage and Family Therapy from Antioch University and has an extensive history working with agencies throughout New York City, New Hampshire, and Connecticut providing marital and family therapy and mental health care.

When not working, she teaches several safety courses specifically geared towards women and business owners. Linntoya and her husband have three children who keep them very busy!
