Cheryl Yarrow

Office Manager

Cheryl Yarrow serves as the office manager of Marble Retreat and is the friendly voice on the other end of the phone in our office. Cheryl and husband Daryl reside in Glenwood Springs. After a 15-year hiatus to raise their two daughters, soon to be college graduates, Marble Retreat welcomed Cheryl back on staff Spring of 2018. Cheryl grew up in Florida, and after graduating from Wheaton College (IL) as a political science major, moved to our Nation’s Capital to be salt and light. There she served leaders in both ministry and public service and was active in reaching out to congressional staff and congressional interns. In 1995, God led her across the country to join the Marble Retreat staff, ministering alongside founders Louis and Melissa McBurney, initially as hostess in the retreat lodge. After seven years of serving in a variety of capacities, including using her administrative gifts, Cheryl “retired” to focus on her growing family. Her passion for Marble Retreat and heart for those in ministry never waned over those years, and she’s delighted and grateful to be part of the ministry team again.


ONE GOD, Creator and Sustainer of all things, Who exists in three Persons — Father, Son, and Holy Spirit.

THE BIBLE as the inspired revelation of God and final authority for living out our faith.

THE DEITY AND HUMANITY OF JESUS, his sinless life, and his miracles; his atoning death and his bodily resurrection provide the only ground for justification, forgiveness, and salvation.

THE ONGOING WORK OF THE HOLY SPIRIT in convicting, empowering, comforting, and guiding believers.

THE UNIQUE AND INVALUABLE WORTH of each individual based entirely on God’s love and grace.


Marble Retreat was born out of the conviction that clergy and others in Christian service, have extreme job demands which can frequently result in symptoms of depression, anxiety, frustration, discouragement and burnout. Worse still and because of their position, they find it difficult to seek help.

These factors, and God’s call, led Mayo Clinic-trained psychiatrist Louis McBurney, M.D. and his wife, Melissa, to begin the ministry of Marble Retreat in 1974, over 40 years ago. Marble Retreat has now served the Christian counseling needs of more than 5,000 Church leaders who have come from every state and more than 60 countries.

In 2003, Steven Cappa, Psy. D., L.P.C., and his wife Patti Cappa LMFT, CAC II, stepped up to carry on the rich legacy of Marble Retreat, assuming the duties as directors, where they served 10 devoted years.

In 2013, Marble Retreat was proud to welcome Drs. Mike and Kari MacKenzie as the new directors of Marble Retreat! They have brought a rich and deep conviction of caring for clergy and believers at large. They had served the ministry since 2007, before stepping into their new roles as Directors.


Melissa McBurney is co-founder of Marble Retreat. She adds to this her experiences as an author, conference speaker, homemaker, and mother of three adult children (Bruce, Andrea, and Brent) and a delighted grandmother! She adds decades of Christian counseling experience to her BA from Baylor University and when she served alongside Louis brought to group sessions her valuable insights, rich female perception and deeply personal spiritual maturity.

The late Dr. Louis McBurney, co-founder, received his BA and MS degrees from Baylor and his MD from Baylor College of Medicine in Houston where he was named Outstanding Student in Psychiatry. He was chosen the Outstanding Intern in Internal Medicine at Houston’s Methodist Hospital. After three years as a General Medical Officer in the Navy, Dr. McBurney completed his psychiatric specialty training at the Mayo Clinic. There he was chosen by the Mayo Psychiatric Section and the American Psychiatric Association for a Faulk Fellowship.

While at Mayo, Louis and Melissa became aware of the pressures felt by those in Christian ministry. From that awareness grew a conviction of God’s call to establish a Christian counseling center for clergy and their spouses. After a year of further training in London, they ventured out to the Colorado Rockies to answer that call. In February 1974, the first group was held and, over time, Marble Retreat became a reality.

Dr. McBurney was certified by the American Board of Psychiatry and Neurology (ABPN). He wrote numerous articles and books including: Christian Sex Rules: A guide to what’s allowed in the bedroomEvery Pastor Needs A PastorCounseling Christian Workers, and Real Questions, Real Answers About Sex (Zondervan Book Publishers).

On January 20, 2009 Louis McBurney quite suddenly and shockingly succumbed to head injuries he’d unknowingly suffered approximately two months earlier, the result of a fall he suffered while descending his garage attic ladder.
