Owner + Occupational Therapist

I was born and raised in the Lake Sunapee region and feel incredibly lucky to now be raising my own family here. Creating Living in Motion has allowed me to combine my love of pediatric therapy with my deep connection to this community, and I’m so excited to support local children and families.

My occupational therapy career began in pediatrics in 2012. In 2016, I joined the Dartmouth Hitchcock Rehabilitation team, where I spent the next decade working with individuals with complex neurological and orthopedic conditions. My experience across pediatric and adult rehabilitation has shaped my ability to meet each person where they are at, recognize their unique strengths, and build from there.

Throughout my career, I’ve seen that meaningful progress happens when people feel supported, capable, and connected. Living in Motion reflects my belief that children learn and grow through movement, play, relationships, and everyday experiences.

The name Living in Motion also holds special meaning to me: the L and M are a tribute to my daughters, Lucy and Madison, who remind me every day of the joy and wonder of childhood.

Occupational Therapist

I’m an occupational therapist, husband, and dad of two, and I’ve always considered myself a kid at heart. My experiences as a father, occupational therapist, and paraprofessional have deepened my passion for helping children and families thrive.

My work in acute care and school-based settings has shaped my interests in sensory processing, movement and coordination, executive functioning, and emotional regulation. I strive to help children and families develop the skills they need to participate more fully in the lives they want to live. My goal is to help give kids and families the skills they need to live the life they want.

Outside of occupational therapy, I enjoy soccer, Legos, Disney, and creating obstacle courses with my family. I love bringing that same sense of movement, curiosity, creativity, and play into my work with children.

Looking Ahead

Living in Motion currently provides occupational therapy, with plans to thoughtfully grow into a collaborative space where children and families can access therapy, education, and community support under one roof.

Future services and programs may include:

  • Physical and speech-language therapy

  • Equine-assisted movement therapy

  • Developmental and school-readiness groups

  • Parent education and workshops

  • Postpartum groups supporting infant development and parental well-being, led by an occupational therapist and licensed clinical social worker

Above all, we want Living in Motion to be a place where children feel understood, families feel supported, and every child grows confident in their ability to do hard things!
