After a breezy four-year tour in the Army, Peter earned a BS in bio- chemistry and molecular biology from the University of Wisconsin - Eau Claire and a PhD in biological chemistry from Indiana University With science seething in his DNA, he sought to infect others with a sense of molecular wonderment.

Having taught, tutored, and mentored in classroom and laboratory environments, Peter was happy to find a home at Fusion Learning Center and Fusion Academy. There, he enjoys persuading students that biology and chemistry are in fact fascinating journeys, not entirely designed to inflict pain on hapless teenagers. His military training occasionally aids him in this effort. A graduate of the University of South Florida, Michelle found her niche early and at 19 was already working with emotionally disturbed and learning disabled students in hospital settings.

At 21 she made the trek to California, and there she found her passion for helping teenage students become more successful in school and life. What started as a small tutoring business in the garage of her California home quickly expanded and grew to the point where traffic control was necessary on her residential street. Michelle has overseen dozens of pro- grams over the last 20 years, focusing on helping kids become healthy adults.

She currently specializes in motivating unmotivatable adolescents, comforting their shell-shocked parents, and assisting her staff of 35 teachers. Years later, he finds himself the Science Department Head at Fusion and oversees a staff of 1 1 science teach- ers.

The graft is prepared from the frilled mantle edge of a living healthy oyster that has a proved merit of highly nacre secreting capacity. The thick outer edge of the mantle is cut off and the tissue is made smooth. The remainder thin portion of the mantle tissue is trimmed to the size of 2 to 3 cm long narrow piece.
