Challenge Mathematics Program
1993-2005
The purpose of this
program is to promote mastery of basic skills in mathematics. I developed and directed this popular
program for this region.
Approximately 10,000 students in grades four through eight from Mahoning,
The purpose of this one-day event is to celebrate the beauty and power of mathematics with 300 high school juniors and seniors from the region. At MathFest, students participate in workshops, a mixed team competition, and a school competition. Workshops include topics such as the golden ratio, mathematical puzzles, game theory, population dynamics, complex numbers, and infinite series and students may choose to participate in two of them. Students will also have the opportunity to participate in an essay contest stemming from a reading list and/or a poster competition involving data analysis and statistics. Our mathematicians present information on careers in mathematics. Prizes and awards are given for winners of the various competitions and contests.

Hermitage Fast Pitch Softball Association
2004-2006
I was the secretary and a coach
for the Hermitage Fast Pitch Softball Association. I was responsible for player
registration, fees, uniform orders, equipment, field maintenance, and management
of a 14U softball team.
Approximately 80 players participate in the association. The past two years, my team finished
2nd in the league. In
2005, my all-star team won a bronze medal at the Keystone Games -

2004-2007
I am the founder and manager of an elite fast pitch softball team. Last year, the team won a berth into the Pony National Softball tournament. Since then, they have won or placed in several tournaments. They recently became co-champions in the Thunderplex Winter Softball League. Most of the members of this team will play softball in college.
