Occupational Therapist

Tish Graf

Tish Graf is a pediatric occupational therapist who values the beauty and individuality that resides within each of the clients she is privileged to work with at MPJ OT.  She is a play-based, family-centered therapist who has a strong interest in a nature-based approach which seeks to use the outdoor natural environment as a co-facilitator of the therapeutic process . Using this mindset, she believes nature is part of the therapy, not just a place to be during therapy. Tish has an undergraduate education degree from the University of Michigan, a master’s degree in audiology from Rush University (Chicago), a master’s degree in occupational therapy from Western Michigan University, and is a DIR Floortime® practitioner.


Tish is a life-long learner who had jobs working with horses, as a pastry chef, and as a yoga studio owner/ instructor. She continues to learn about the dynamic field of pediatric occupational therapy by attending courses and conferences including the SOS Feeding Conference; American Hippotherapy Association level 1 Treatment Principles Course;  Sensory Integration Network SI module 1 (Foundations & Neuroscience); and Handwriting without Tears.


When not working, you can find Tish walking in the woods, visiting with friends, talking to her daughter (who is the absolute joy of her life),  or dressing the part of an 1890’s farmer while volunteering at a historic farm in West Chicago, IL.
