Upon the move to Denver, he switched career tracts beginning a job at UDR, a publically traded multifamily REIT based in Highlands Ranch, CO.

Diana Guetig earned a Master of Education in Gifted and Talented Education and a Bachelor of Arts in Early Childhood Education at George Mason University in Virginia.  She taught kindergarten and third grade in Fairfax County Public Schools before moving with her husband to Colorado in 1994.  Diana stayed at home helping to raise their three boys for seventeen years.

Diana was introduced to Charlotte Mason’s philosophy of educating children when looking for a school for her third son.  Impressed by the approach to learning, she not only enrolled her son but also became a teacher in the opening year of Ambleside Colorado.  She taught third and fourth grades for several years at Ambleside. Since then, she has continued to support students and teachers at Ambleside by spending many hours in a volunteer role to assist, train, and substitute in the classrooms.

Dr. Bill St. Cyr’s academic and professional life has centered on the process by which men and women grow to a maturity which reflects the person of Jesus. His academic pursuits have included political philosophy (B.A., Louisiana State University), historical theology and spirituality with an emphasis on the patristic period (M.A., Catholic University of America), and pastoral counseling (M.S. and Ph.D., Loyola of Maryland).  Bill has been a youth minister, provided leadership to a discipleship ministry on Capitol Hill, served as assistant to the Chaplain of the United States Senate, and spent thousands of hours counseling committed believers whose life experience has been something less than love, joy, peace, patience, and kindness.  Since 2001, Bill has been working with his wife to foster a reformation in education.  He currently serves as Executive Director of Ambleside Schools International.

Co-Founder – Kimberley Lorden and her husband Greg joyfully co-founded Ambleside School of Colorado in 2010, where she served as Director of Admissions through 2016 and as a board member until 2019. Kimberley discovered the beauty of a Charlotte Mason education when her children began attending an Ambleside School in Virginia in 2000. Her parenting and marriage were transformed through what she learned. In 2003, Kimberley began to serve on the Board of Trustees of that school, which she found to be a rich and life-changing experience.

In 2006, the Lorden’s moved to Littleton, Colorado, and in 2008 they briefly home-schooled their children, ages 4 to 13, as the family traveled for most of a year in a motorhome through the US and Canada. After experiencing other schools, they realized how unique Ambleside’s education is for children, and they began to pray for the Lord to open doors for such a school to be established in Colorado!

Kimberley has an MBA in Finance and a BSBA in Business Management from the University of Denver. She worked for Shearson Lehman between her degrees and then moved to Washington, DC where she worked for a Member of Congress as a Legislative Director and Ways and Means staff for six years, until her first child was born. After this she spent the majority of her time raising three sons and a daughter with her husband, Greg. Kimberley loves Ambleside’s educational philosophy, her church, reading, hiking, skiing, and finding adventures while exploring with family and friends.

Chaplain – Dr. Bentley Tate has practiced as an Emergency Medicine Doctor in Colorado since 1993, but he has most enjoyed investing in his family and ministry pursuits. He holds an M.D. from the University of Maryland Medical School (1990) and completed specialized training at the London School of Tropical Medicine (1994). After medical training, he obtained a Master’s of Divinity from Denver Seminary (1999). In 2000 he traveled to the country of Myanmar and quickly sensed he was to have a longer-term involvement there. He co-founded Asia Heartbeat in 2003, a non-profit ministry caring for orphaned and abandoned children in Myanmar.

For the last decade, Bentley has been Director of the ER at Colorado Plains Medical Center in Fort Morgan. His leadership roles in the last 15 years have included serving as President of the Board of Alternatives Pregnancy Center, Elder in his church, Licensed Preacher in the Presbyterian Church of America and President of Asia Heartbeat. With three of their four children at Ambleside Colorado, he and Sandra, his wife of 18 years, seek to return the blessing the school and its people have been to them.

Instructional Philosophy Consultant to the Board – Leesa Waliszewski served Ambleside as its beloved founding Principal beginning in 2010 and continued in that role until 2016 when she became a Board member for three years. Leesa also works with Ambleside Schools International to support member schools. Prior to coming to Ambleside, Leesa served for a decade as the Dean of Instructional Philosophy overseeing the curriculum, educational methods and approach to instruction at The Classical Academy’s five campuses in Colorado Springs, serving over 2500 students. After graduating from Oral Roberts University with a BA degree in Elementary Education, she obtained her Colorado Teacher certification and taught for five years in the public school system in the Colorado Springs area. After the birth of her children, she enjoyed being a stay-at-home mom and eventually homeschooling her children for several years. In 1997 she joined the inaugural staff of The Classical Academy (TCA), a charter school in north Colorado Springs. In the third year of its existence, she started TCA’s Cottage School program, partnering with homeschooling families in the area. Leesa considers it a “dream come true” to have the opportunity to serve children, families, and staff in a school with Charlotte Mason’s philosophy and a Christ-centered atmosphere.
