Mrs. Donelle Wiechman

I am a 13 year resident of the area.  I am married with 3 children and much of my family lives in the area.  My oldest two children are currently in college and my youngest child is a high school freshman.  I have a sister and 3 brothers, all of whom graduated from PSHS.  My undergraduate degree is in electrical engineering from Texas A&M.  I also have a masters degree in business administration.  I worked as a product/test engineer for about 15 years for Texas Instruments before becoming certified to teach secondary education.  I have been teaching at the secondary level since 2009 and have been at Plano Senior High School since 2016.  I enjoy working with high school school students and hope that my students develop an appreciation of math and the power that it gives them to solve problems.
