    Hello to All OT Families,

    My name is Mary Holzer-Doerr and I am an occupational therapist at Westchester Hills School. This is my 20th year at this school, and my 38th year working as an occupational therapist.

    If your child is receiving OT service, I will be focusing primarily on the goals which are identified on their IEP. These goals may include activities involving sensory processing, fine motor, visual-perceptual motor, graphomotor (handwriting), and ADL (activities of daily living) skill development.

    I look forward to working with your children, and I thank you for your support. If you have any questions, please feel free to contact me at my school e-mail during school hours.

    Wishing you and your children a wonderfully exciting and productive school year.

    I look forward to meeting you at Open House,

    Mary Holzer-Doerr

  • Hello OT Families,
    I have been uploading thematic monthly modules for you to use as a supplement to our sessions at school and/or on line. The word document is here on Blackboard, with a few activity suggestions and links. The complete module with coloring and activity pages is available on my Teams page, under "OT Monthly Modules."
    Wishing you all a wonderful and healthy school year,

  • 3/13/2020     Dear OT Families,

    Attached above please find various occupational therapy related activities for your child to do during this extended school closure.  I will be posting daily assignments which you can find under  "Assignments."  Detailed instructions for the assignments can be found under "Classroom Expectations."  Thank you for your continued support during this time. Please contact me if you have questions or concerns at my school email:   I am available Monday - Friday 8:30 am - noon.

    Please know that our school pets are safe and being cared for during this interim period. The ducks and turtle are at my friend’s farm. The fish tank ecosystems were deemed to be self-sufficient, and the custodians will be feeding the fish. The ducks and turtle will return to WHS-29.
