Abriana Iwanski

English Language Arts Teacher

I was raised in a family who considers education to be a top priority. In addition to that and several experiences with extremely influential teachers, I decided that teaching was what I wanted to do. I graduated from Eastern Illinois University with my Bachelor of Arts in English and a secondary teaching certificate. I was always interested in teaching underprivileged or struggling youth, which is what led me to CALO. I have always held the core belief that relationships are the key to almost everything in life, including education. I felt so lucky to find a place like CALO that shares this core belief. I look forward to many years of helping students to find value in education and to learn how to build healthy relationships in all aspects of life.

Ali was born and raised in the St. Louis area.

After high school, she attended Lindenwood University and graduated with her Bachelor of Science in Chemistry with a Concentration in Biochemistry. She is certified to teach science and math. In 2014, she moved to the Lake of the Ozarks where she worked as a water quality control chemist before coming to Calo in 2015. She is married to her high school sweetheart. They have two young daughters, Charlette and Sophie. She also has two fur babies (Lady and Duke). In her free time, she enjoys being outdoors- swimming, boating, and fishing here at the Lake.

Paula Tyler B.S


I was born and raised in the small farming community of Mary's Home, Missouri. After high school I married my best friend, Wendell. We have 4 sons, Jacob, Eric and the twins, Joseph and Thomas. When the twins started school, so did I. I worked full time as a paraprofessional and attended Columbia College where I received my B.S in Business. While working at the school I realized that teaching was what I really wanted to do. So I attended MU and received my teaching certification. I spent the last 20 years teaching math at Cole R-V Eugene public school. After 20 years it was time for a change. I love working with all kids, but my heart lies with working with the kids who really need the most love and attention.
