Meet Our Executive Team

  • Carolyn

    Executive Director

    Meet Carolyn…

    Carolyn wants to live in a world where tolerance, acceptance, and inclusion are standard practice, and people are kinder than necessary.

    As the Executive Director, she’s responsible for guiding the agency with a mindful and cohesive vision. She strives to ensure that CDC is known for its staff expertise, consumer satisfaction, and community contributions.

    When she’s not in the office, you might find her getting lost in the wilds of Glacier National Park, summitting a peak in the Jewel Basin with her husband and kids, or roasting marshmallows over a fire at her backyard in Florence.

  • Catherine Hafliger

    Catherine Hafliger,
    Evaluation & Diagnostic Services Clinic Director

    As the E&D Director, she oversees all new referrals as well as CDC’s evaluation clinics in Missoula, Kalispell and Bozeman. Catherine is passionate about connecting families with the education and supports they need to enhance their lives.

    When she’s not at CDC, you can find Catherine making snacks and chasing her two boys around!

  • GREG MALONE

    Greg Malone,
    Chief Financial Officer

    Meet Greg…

    Greg wants to live in a world where Debits and Credits can all get along, payroll always runs smoothly and insurance companies and providers coexist in obtaining the best possible outcomes!

    Seriously though, Greg came to CDC as the CFO to streamline business practices, so that staff could focus on CDC’s mission: helping children and families.

    When he’s not pouring over financial data and spreadsheets, you can find Greg in a gym or on a football field rooting on his sons.

  • Jenny Vickhammer

    Jenny Vickhammer,
    Autism & Behavioral Services Director

    Meet Jenny…

    Jenny Vickhammer wants to live in a world where each person is empowered to harness their unique strengths so they can build up themselves, their friends, families and communities.

    As the ABS Program Director, Jenny works hard to make sure children across western Montana who are diagnosed with autism receive the best possible services. She oversees support not only for individual children and their families, but also community and school-based consultations and trainings.

    In her free time, you can find Jenny on family adventures, running and kayaking, watching TED talks or reading the latest fiction best sellers.

  • Karlyn Gibbs

    Karlyn Gibbs, Treatment Director

    Meet Karlyn…

    Karlyn wants to live in a world where mornings start a little later, square pegs aren’t required to fit into round holes and every child has at least one adult who is irrationally crazy about him or her.

    As the Autism & Behavioral Services Treatment Director, she’s responsible for assuring that children with autism spectrum disorders and other disabilities receive the support and training they need to succeed. Karlyn is a Board Certified Behavior Analyst (BCBA) and has been instrumental in the pioneering of autism services in the state of Montana.

    When she’s not working, you can find Karlyn gardening meditatively in her flowerbeds, absorbed in a thick novel, sewing like a mad woman, searching for the best fare for her next trip to Seattle and reflecting dreamily on the perfection of her grandchildren.

  • Lea Shanks

    Lea Shanks,
    Children’s Waiver Services and
    Family Education & Support Director

    Meet Lea…

    Lea Shanks wants to live in a world where kindness, dignity and respect are at the forefront of all interactions, and each of our unique strengths are celebrated.

    As a director, Lea oversees the implementation of policies, budgets and support plans that impact the children and families in her programs. She guides Family Support Specialists through the challenges and triumphs of their roles, providing assistance with crisis situations and developing and training on front-line behavior interventions.

    When she’s not multitasking at CDC, you can find Lea directing a local theatrical production, shuttling cub scouts, hosting friends and family around a backyard bonfire and rocking out to the 80’s in her minivan.

  • Sue Holmstrom

    Sue Holmstrom,
    Early Intervention Director

    Meet Sue…

    Sue Holmstrom wants to live in a world where everyone gets along with one another, is accepted for who they are, and has free access to needed services that improve their well-being.

    As the Early Intervention Director, Sue is responsible for guiding Family Support Specialists and trying to keep them happy. She also has the fun job of making sure all Federal and State requirements are being followed…

    When she is not collecting data, you can find Sue outside: she loves camping, hiking, skiing, snowshoeing and watching GRIZ football. When the weather is really bad she likes to do crafty things.

  • Teresa Beeton

    Teresa Beeton,
    Human Resources Director

    Meet Teresa…

    Teresa Beeton wants to live in a world where policy invokes tears of joy, benefits are plentiful and people don’t refer to her discipline as IHR (Inhumane Resources).

    As the HR Director, she aligns human resource goals to support CDC’s mission. Policy, benefits, recruitment and employee relations fill her time. In short, Teresa works hard for CDC’s people, so they can work hard for CDC’s clients.

    When Teresa’s not neck deep in HR, she’s bowling with her family, defending her air hockey title, rooting for the LA Lakers and enjoying every crazy moment her three boys and husband throw at her.

Meet Our Program Coordinators

  • Cassandra Schroeckenstein

    Cassandra Schroeckenstein,
    Early Intervention Coordinator

    (Kalispell area)

    Meet Cassie…

    Cassie wants to live in a world where webinars and paperwork are nonexistent, and every child and family receives the help they need, regardless of funding or red tape.

    As the Early Intervention Coordinator, she’s responsible for training and supporting Early Intervention Family Support staff. She also maintains her own small caseload.

    When Cassie isn’t coordinating, you can find her walking her dogs and spending time with her husband.

  • Hollin Buck

    Hollin Buck,
    Early Intervention Coordinator

    (Missoula area)

    Meet Hollin…

    Hollin Buck wants to live in a world where people care more for each other and the places we live, and less for money and things.

    As the Early Intervention Program Coordinator, Hollin supports our Family Support Specialists and keeps up to date on best practices for helping children and families.

    When she’s not at CDC, you can find Hollin in the Montana wilderness on her bike, skis or feet, reading anything she can get her hands on and delighting in her daughter and family.

  • Jamie Eff

    Jamie Eff,
    Autism & Behavioral Services Coordinator

    Meet Jamie…

    Jamie Eff wants to live in a world where skill acquisition programs are plentiful, reinforcers are reinforcing, behavioral data graphs itself and all the “what-ifs?” have answers.

    As the ABS Program Coordinator, she spends her time training and supporting staff, overseeing Kalispell CDC’s two on-site centers and continuously working to provide quality services to children and families.

    When she’s not “coordinating,” you can find Jamie playing with her daughter, engaged in a competitive game of pinochle or soaring through the hills on her motorcycle.

  • Linda Roundy

    Linda Roundy,
    Children’s Waiver Services and
    Family Education & Support Coordinator
