I was a high school mathematics teacher at Spring Lake Park High School (SLP, MN) for 40 years. I taught a variety of courses and filled numerous extracurricular roles. Currently, I am the Executive Director of the Minnesota State High School Math League.

I dabble recreationally in mathematics, trying to extend or create novel mathematical ideas. In 1995, I believe I was the first to propose a new coinage system, with the dime being an 18 cent piece.

The idea of a non-self adjacent path was originated by me and then explored extensively by Christopher Hunt Gribble. Currently, I am working on n-cell tiling of an n X n square

My contributions of ideas include:

      A014062  a somewhat irrelevant comment on an application of the sequence
      A047838  Definition of the organization number of a sequence.  More so, the disorganization
      A051437  Contribution of a paper on quilt pattern symmetry that produced the same values as the defined sequence on undirected walks
      A165217  a conjecture as to the formula for the even entries in the sequence
      A320422  number of tiles inside a regular n-gon created by diagonals that run from each of the n vertices to the n-2 midpoints of opposite edges
      A179094  the disorganization of numbers in an n X n array
      A320431	The number of tiles inside a regular n-gon created by lines that run from each of the vertices of the n edges orthogonal to these edges.
      A178842  Number of ways to place n objects in an (n-1) X (n-1) array (e.g., the number of ways to arrange stars in a flag's field pattern).
      A363381  a(n) is the number of distinct n-cell patterns that tile an n X n square.
      A364607  the best 4-coin system for change for a dollar      

Several entries by Christopher Gribble about non self adjacent paths which sprang from an idea I proposed. He gives credit to me in the introduction of his Wiki page
