About Us

Residential and Community Support Services (RCCS) was founded by Christine Tiernan and a Board of Investors in April of 2013. Based on the foundation principle that a “human services” organization should try its utmost to serve the people it supports directly, and, critical to its success, support the teams of professionals that work with those individuals.

With the desire to create the most person-centered programming available, and serve each individual in their current state upon arriving at our program, RCCS works on the individual level in helping clients develop into the person they envision. We work directly with each person we serve to help them set clear goals, and then work incrementally toward each goal so that they may realize success along their journey.


Organizational Structure

RCSS is an organization with a small executive team and only three layers of organizational structure. We believe this allows us to maintain our vision for service to our clients and employee support best. As the organization grows, some structure may be added, but the expectation is that the distance from the ‘agency founders’ to the newest employee will never be more than two layers of supervision.
