About

I was raised on a peach farm of 3500 trees. This is where I got my work ethic and love for pets. My identical twin and I built houses together for 17 years. We then decided to go to college. He went for banking while I got my degree in Chemistry.

I concentrated on polymers. I love fishing from a kayak and breeding fish, guppies. Our Mother ran a clothing store called Mania. It was for people who needed clothing but could not afford them. Twin Brother currently runs a food pantry.

I am never late and not afraid of a lot of hours. I hope to get a job at Salvation Army to help all who need it.
