The Director

The Center Director, at Mathnasium of Riverview, is a retired engineer, with experience in civil/environmental and mechanical engineering.   

He is an avid volunteer, and gives his time freely to mentor and teach young people.

As a substitute teacher at the Kid's Community College- Southeast campus teaching K through 4th grade, he continually volunteered to help maintain and repair the facility.  Making sure the kids had a safe and clean environment to learn, the Campus Director was so pleased with his teaching and demeanor with the kids that she hired him as the Director of the after-school program Impact Children For Life (ICFL). 

Soon afterwards, it became clear what he wanted to do- teach kids full time and concentrate on math, engineering and sciences.  The idea of the Mathnasium of Riverview was born.

He has a way with teaching kids and keeping them focused and curious.  He is very compassionate and wants to see EVERY kid get their fair chance at success through math sense.  

He feels that every kid can succeed at math if they are taught in a way that actually makes sense to them as an individual! 

And at Mathnasium, we make math make sense.

 His credentials :

- Certified instructor at Mathnasium

- Bachelor of Science in mechanical engineering

- Master of Science in environmental engineering

- Math Teaching Certificate of eligibility from Florida Department of Education

- Former elementary school substitute teacher and Director of after-school care program

- Published research in fluid dynamics, heat transfer, rheological properties of simulated nuclear waste

- Fellowship recipient from the US Environmental Protection Agency (US EPA) 

- Air quality engineer in training, for the US EPA, at Research Triangle Park, NC
