I have been a "science geek" my whole life and see no reason to change now. I received my Bachelor's of Science degree from UNL in 1993. I proceeded to take graduate classes in physiology and earned a Master's degree in secondary teaching in 2005. If you need to contact me you may do so at 284-9900 or at jyork@esu16.org Remember: Success is biting off more than you can chew..... and chewing it!
