The Mathematics Department includes faculty members whose degrees and experience extend beyond mathematics and mathematics education to disciplines that include physics, computer science, logistics, economics, business management, applied statistics, accounting, actuarial science, instructional technology, educational administration, political science, communication, and English. A very dynamic and versatile group, the faculty has a median of 20 years teaching or other related full-time work and all belong to at least one professional organization such as the American Mathematical Association of Two-Year Colleges (AMATYC), the Mathematical Association of America (MAA), the National Council of Teachers of Mathematics (NCTM), the American Mathematical Society (AMS), the American Statistical Association (ASA), and the National Association for Developmental Education (NADE).

**Education**
- B.A. in Psychology, University of Illinois
- M.B.S. and M.S. in Mathematics/Statistics, University of Colorado

I came to Penn College in 2009 after 30 years of teaching secondary mathematics in Colorado. In addition to teaching here, I am studying mathematics education at Penn State University. My area of research is developmental college mathematics. My favorite saying is "It is OK to not know something. Whatever the topic, nobody knew it before they learned it. We are all in the process of learning."

I joined the faculty at Penn College in 2009, after more than 20 years in education. I began teaching at the University of Wisconsin – Milwaukee, and left there to teach high school in Kenya for two years. Following that I taught in the public schools of Wichita, Kansas, before this return to college. I describe Penn College students to others as "students with clear goals and plans," and it is my privilege to help students along their way.
