Angela Rosenburg, OTD, OTR/L

Occupational Therapist
TimberNook Program Director

Since starting her career in 2004, Angela has passionately worked with children across Central Florida to help them achieve their best!  After years in the schools and clinics, Angela is driven to level up the therapy process by taking services and programs into nature — drawing on the rich therapeutic opportunities wild, natural spaces provide!  Angela believes therapy should be fun & functional, goals should be meaningful to the child and parent, and she has found that outdoor groups provide real interactions and real skills that cannot be replicated in the clinic.  By taking therapy and programs outdoors,  Angela has observed tremendous transformations of sensory, motor, social, emotional, and cognitive skills.  When not in the woods, Angela can be found at home with her husband and 3 kids playing games, building with blocks, and planning their next adventure.
