I have a background in science and math. I graduated with a PhD from the University of Notre Dame, an MS from the University of Wisconsin-Milwaukee and a BS (summa cum laude – with highest honors) from the Inter American University of Puerto Rico. My major subjects were Physical Chemistry, Analytical Chemistry and Chemistry.

I worked for many years at Bayer and at Hach Company in Elkhart. My team developed products used to analyze different materials. These products are used in clinics and medical offices around the world. We developed new chemical testing devices for analyzing water in the environment, in industry and in pools and spas. I also developed complex mathematics used in electronic instruments. I hold several U.S. and foreign patents; the most recent issued in April 2014.

For many years, I was a youth soccer coach in the Concord league and was a player in an adult soccer league. I create YouTube videos for fun, information and training purposes. My wife and I raised two children who graduated from Concord High School and Purdue University, and went on to earn graduate degrees.

As a math teacher, I have had the satisfaction of seeing students see the light, find their way in math, and start to explore and blaze new trails of their own. I help others to see math clearly. I tutor all levels of algebra. I also teach online and traditional math classes at Ivy Tech Community College in Elkhart and South Bend. My philosophy is that every student is capable of learning and applying math principles. My passion is to provide a boost to get them going.
