Angel Bowling Horn

Executive Assistant
Angel Bowling Horn loves working with people and helping them learn and grow.  She’s especially fond of leadership development through transformational learnings. She is a graduate of Morehead State University where she obtained her undergraduate in Education and later returned for graduate classes in Adult and Higher Education.

She began teaching elementary aged children and planned to work with kids the rest of her career.  One summer, her life took a different turn when she accepted an offer to teach a new Electronic Medical Records system to staff at a large regional medical center.  It was there that she found her true calling in adult education and corporate training. 

Angel lives in rural eastern Kentucky, literally surrounded by hilltops of home and family. She is married to her high school sweetheart and they have two teenage children.  She enjoys reading, cooking, and traveling, and in the summer you can generally find her soaking up the sun while boating and fishing on the lake.

She is often called on for administrative consultation in her father’s business.  In addition to a close-knit family and extended family, Angel’s faith in God is very important to her.  She’s a longstanding member of her church and is frequently working in her community through church events and by teaching the ladies in Sunday School.  In her spare time, she loves to bake cookies for her many nieces and nephews.
