7th Grade Team

Jennifer HostetlerI’m Jenn Hostetler and I teach Literacy in 7th Grade.  While I was born and raised in Massachusetts, the Western Slope has been my home for 22 years.  I feel blessed to live, work, play and raise a family here in New Castle.  I have spent the past 20 years teaching middle and high school in the valley and can’t fathom doing anything else!  I am most thankful for the unique perspectives, creativity, and laughter that students share with me every day.

Emily AnderleI’m Emily Anderle. I became a literacy teacher because I believe in the power of words to make the world a better place and because I love a good story. This is my 13th year teaching at Riverside. I’m married and have two sons, William (8) and Luke (5) and 1 more on the way, due October 30th. When I’m not at school, I’m usually watching my kids ride bikes at the skate park or reading on my porch.

Social Studies

Bryan Gall

Bryan Gall here! I’m a Chicago Native that’s lived in Colorado for over the last twenty years. I’ve been in New Castle since 2003. This is my twenty second year teaching; I’ve spent time teaching in Glenwood Springs, Coal Ridge High School, and I’m happy to now call Riverside my home. I teach 7th grade Social Studies which focuses on ancient word history and outdoor education.

I live with my partner Amy, my two wonderful children, my partner’s amazing daughters, and a menagerie of pets. Feel free to say hello if you see us riding bicycles to school. You might run into me outdoors climbing with the Titans of Climbing, our Coal Ridge/ Riverside climbing club, mountain biking on the wonderful trails built by New Castle trails, floating the river by paddle board or raft, or snowboarding at Snowmass or Sunlight mountain. Don’t forget to be awesome! Phone:  970-665-7826 Email:  bgall@garfieldre2.net

Bob StewartMy name is Bob Stewart and I teach 7th Grade Science. While I have lived in Western Colorado for the last 28 years, I spent most of my youth living overseas from Africa to Asia.  This is my 13th year at Riverside; 2 years teaching math and the last 11 years teaching science.  Prior to Riverside I spent several years teaching high school level science.  My degree is a Bachelors of Science in General Biology from Fort Lewis College in Durango. Besides teaching I love to travel, raft, SCUBA dive, cook, fly fish, and tie my own flies. On most weekends you can find me float fishing the Colorado or Gunnison River.

Chris OzminkowskiHi there, my name is Chris Ozminkowski. I teach 7th grade Science here at Riverside and I love it!! I’ve spent most of my life in the midwest frequenting Wisconsin, Michigan, and Minnesota but ever since I’ve made it out to Colorado, I don’t know of any better place to be. I coach Track here at Riverside and Cross Country at Coal Ridge High School so if you are a runner, or maybe one day turn into one, you'll see me! You may also find me climbing rocks or ice somewhere in the area. New Castle is incredible, Riverside is incredible, and I suppose that is all you really need to know.
