Welcome!  I am proud to be a science teacher at Holland High.  I have been here since 2003, after receiving my Bachelors of Science in Biochemistry from Texas A&M University. 


I have been married for 23 years and have two children (Samuel Jr. and Victoria).  Samuel is attending Louisiana State University and Victoria is seeking a degree at Concordia University.


I teach Biology, Anatomy & Physiology, and Engineering at Holland High.  I love science because it is always changing and I feel that an effective science lesson requires planning engaging activities, navigating tricky science concepts, anticipating and working with students' preconceptions and misconceptions, and making difficult decisions on the fly.

Class Resources

Course Description:  Biology is devoted to the study of living things and their processes.  Throughout the year this course provides an opportunity for students to develop scientific process skills, laboratory techniques, and an understanding of the fundamental principles of living organisms.  Students will explore biological science as a process, cell structure and function, genetics and heredity, evolution and classification, diversity of living organisms and their ecological roles, and as introduction to animal structure and function.  An end of course test (EOC) will be administered in May, which covers objectives for both semesters.

Welcome to Engineer Your World!

This class will engage you in authentic engineering practices in a project-based learning (PBL) environment.  Learning is scaffolded over a series of engaging and socially relevant explorations and design challenges. The curriculum focuses on creating a 1) narrative of engineering, 2) building engineering design skills, 3) developing engineering habits of mind, and 4) introducing engineering fields and professions.
