Phyllis Johnstone 

Assistant Teacher

My primary career was in banking.  I started out as a Teller at a Savings and Loan and advanced to becoming a Supervisor.  I then moved on to a commercial bank as a Personal Banker opening all types of accounts including Savings, Checking and IRAs for both personal and business accounts.  I also made all types of loans including personal loans and mortgages.   I took many classes pertaining to bank products and leadership, became a bank officer, and had the honor of being employee of the year. In this new phase of my life, I thoroughly enjoy working as a Teacher’s Assistant at SKD.   I do not have any grandchildren of my own so I can adopt all of the children  for the day.  They are so eager to learn and I enjoy working with them in a group setting or one on one.  I think of them as my little cherubs.  The teachers that I work with at SKD are so loving and amazing, I am sure they are angels that have been sent from God.  Working at SKD along with counting collection money and being an EMHC I feel like I practice my Catholic faith every day. Things I like to do for fun are traveling (especially by cruise ship) music, movies and theater.

Christina Christopher

Preschool Teacher

I am thrilled to be a newcomer to the SKD team and feel truly fortunate to be at a place where I can play and pray alongside my students!  I received my B.A. in Organizational Communication with a minor in Leadership Studies from the University of Colorado-Colorado Springs.  Before becoming a teacher, I was a Program Coordinator for the Center for Creative Leadership which gave me great insights into the business world and organizations.  However, after four years God redirected my path to education, and I received my M.A. in Elementary Education from the University of Phoenix.  Before moving to St. Katharine Drexel, I taught Kindergarten & Preschool in the Widefield School District (Widefield, CO)  for several years, was an early childhood teacher at Evergreen Country Day School, and most recently was a 4th grade teacher at St. Mary Catholic School in LIttleton.  Happy to be a Colorado native, I was born in Alamosa and grew up in Colorado Springs.  My family and I moved to Littleton in 2014.  I am married to John, and we have been blessed with 4 beautiful children.  They keep us busy; consequently, family life is my hobby!  We look forward to game nights, movie nights with popcorn and hot cocoa, hiking, camping, a good laugh, trying new recipes, time with family and friends, gardening, and planning for and embarking on summer road trips!  As a family, we also devote much time to various ministries at our parish, Light of the World.
