Who We Are

The OT Collective is a group of pediatric occupational therapists, each of whom brings a different background and unique therapeutic offerings to our clients. The OTs have been hand-picked to join the Collective based on their ability to provide neurologically-based treatments as well as to combine different disciplines and targeted activities into their treatment sessions.

Each therapist has completed training through a renown neurologically-based therapy program, Therapeeds Inc. Each therapist has his or her own established private business, but we work together as a group by providing monthly co-treatment sessions, bi-weekly continued education discussions, monthly Tiny Topics for parents, and weekly to monthly activity groups for children. We are all Medicaid and Imagine! providers.

Natalie M. Mannherz, OTR

Natalie Mannherz is a pediatric occupational therapist and piano teacher who provides consultation services to families who have children diagnosed with neurobiological disorders across the US. Natalie graduated with a Master of Music in Piano Pedagogy in 2007 from the University of Wisconsin-Madison and a Master of Science in Occupational Therapy in 2011 from Boston University. She moved to Boulder in 2011 where she founded a piano and therapy business, Occupational Piano. As Natalie delved more into providing occupational therapy services to children, she became increasingly interested in the neurological reasons behind developmental delays. Natalie focused on completing all of the Therapeeds, Inc. continuing education courses and changed her treatment approach to focus on changing how the brain processes information. In the spring of 2018, Natalie founded The OT Collective with the goal of creating a group of like-minded occupational therapists who could provide neurologically-based services. In her free time, Natalie takes care of her two young sons, skis, hikes, and plays the piano.
