|Meet Our Teachers|
David Chandler – Computer Programming
David Chandler is a career software engineer who has worked for companies such as Intuit and Google. He earned a BS in Electrical Engineering from the University of Kansas and has previously taught math and computer science courses through a homeschool coop in Georgia. Several former students are now pursuing careers in computer science.
David is sometimes known as "Dr. Fibonacci" and loves to point out the mathematical order and information content of the created world, such as the frequent appearance of the Fibonacci series in flowers and trees. David and Vicki Chandler have homeschooled their five children and spent a year in Peru starting an ongoing project to put more biblical resources online in Spanish. They are members of Southside Bible Church in Centennial.
Sandy Edwards – French 1 and 2
Sandy Edwards homeschooled her children for 16 years. Her son attended CCA from 2006 to 2010, and her daughter from 2010 to 2015.
Prior to her career as a homeschooling mom, she was a CPA, after graduating from UC Berkeley with a BS in Business Administration. She has been married for 30 years to Eric, who used to be a business financial executive, and now runs a senior home care company.
Adrienne Hanagan – Biology
Adrienne Hanagan has a Chemical and Petroleum Refining degree from Colorado School of Mines and a Masters' degree in Cell and Molecular Biology from San Francisco State University. She has worked in the aerospace industry, at Sandoz Crop Protection, at Synergen, a small biotechnology company in Boulder, then Supragen in Lakewood, and finally at CU Health Sciences Center for the School of Pharmacy. She worked as a protein biochemist for Professor Carlos Catalano for over two and a half years. She has eight years of experience working in the biotechnology area.
When her son was born 18 years ago, she had a very hard time giving her child to someone else to care for. She thought she would go back to work when her son was a bit more independent, say, at age 3. Well, it didn't happen. She home schooled her two sons through COVA for seven years rather than send them to the local elementary school. It was a thrill to teach her eldest how to read and to do arithmetic. She decided to try homeschooling on her own using an umbrella program, and did that for four years. She enjoys introducing kids to science and math. She volunteers in her son's Young Marines unit as a math and science tutor. There is always one young man or woman who needs help with those subjects.
God is the most amazing scientist and engineer. She realized when getting her Masters' degree that God beat engineers and scientists hands down when he created the simplest bacteria.
Tahla Stephens – Agricultural Science, Algebra 1, Fine Art, Personal Finance
Tahla Stephens has a passion for teaching. Before God blessed her with children, she taught in both public and private schools.

Tahla has been teaching math classes at CCA since 2005, and has recently added Agricultural Science, Fine Art and Personal Finance to her repertoire. She is a Watercolourist and Fiber Artist but enjoys experiencing the creative process in many art media. Tahla strongly believes in mastery of mathematical skills, art and gardening techniques, and financial concepts, and will work tirelessly to make sure her students thoroughly understand the material she teaches. Tahla has a Bachelor's degree in Elementary Education from UNC with a minor in Special Education.
Sallie Surniak – American History/Government 1, American Literature, Government 2, Physical Science, Speech
Sallie Surniak longs to follow in the footsteps of Jesus by helping others, sharing stories, teaching important lessons, showing love, granting forgiveness, and giving God the glory.
Having grown up in a military family, Sallie loves seeing the world and meeting new people. She received a journalism degree from the University of Nebraska-Lincoln, and was a lifestyle editor for a weekly paper and columnist for a daily paper. Yet, Sallie soon discovered that most people read on a sixth grade level or lower, so reading a newspaper and learning new things is a struggle for many people. Coming from a family of teachers, this planted a seed that showed Sallie she needed to go to the people and teach them to read and love learning. After getting married and having three daughters, she became a stay-at-home mom. Her children attended Christian schools, where Sallie volunteered often. When her family moved to Colorado in 2001, she homeschooled all of her children at different times, and thoroughly enjoyed the experience. As her children grew, Sallie taught high school U.S. history and middle school literature at two Christian schools in Parker. She went on to get her master’s degree from the University of Phoenix at Lone Tree in elementary education. Then, she taught third and fifth grade at the charter school American Academy. When she wasn’t busy teaching or subbing in Douglas County during the day, Sallie tutored students after school.
Since then, Sallie has remarried and moved to the Littleton area where she and her husband help raise his two elementary-aged children half the year. Sallie continues to substitute teach and tutor, but she missed the homeschooling environment. God has answered her prayers and led her to Crossroads Christian Academy, where she can teach and give God the glory He deserves as young hearts and minds yearn to understand the truth. With God’s help and the wonderful people at CCA, Sallie looks forward to teaching American History with Government 1, American Literature, Government 2, Physical Science, and Speech this year. May it be a year full of love, learning, and blessings.
