Bringing people and community together since 1992.

TrilliumServices was founded in 1992 by Jim and Wendy Annis. Trillium Services (then Paragon Services) was a small provider, operated out of their home office with six service recipients and two employees.  Over the past 30+ years Trillium has responded to the needs of our community by always trying to find a way to say “yes,” helping where we can, and growing the business when needed.  Today we are proud to offer a wide range of services including residential services, community-based services, family services and respite care, vocational and supported employment services, and professional training and consultation.

Brian and Amanda, the son and daughter of Jim and Wendy, have grown up working alongside their parents for as long as they can remember. Naturally, they came to work at Trillium after high school, and like a lot of our management team here, have held almost every position at Trillium throughout the years. Amanda and Brian are passionate about carrying forward the work their parents started, which became official with the purchase of the business in 2021. Trillium Services, Trillium Works!, our Executive Director team, and all of our stakeholders, remain dedicated to the legacy Jim and Wendy built from day one. Supporting the whole person and their family through our Mission, Vision, and Core Values.

“Trillium Services prides itself on being a second generation family owned and operated business.  Amanda and I aim to carry the mission, vision and core values, established in 1992 by my parents, Jim and Wendy Annis in everything that we do. We are passionate about supporting people;, the people we serve, their families, the people we have the privilege to employ and those we get to work with in the community.  We will be honored to do this work for many years to come.”

Facilitating Independence

Our values encourage personal development, self-determination and community connection. We continually envision new opportunities for the people we support and seek out innovative ways to cultivate greater independence as they pursue their dreams.
