OakHaven Faculty and Staff
Judy Henrichs
Head of School
Judy has a rich background in the business and education worlds. In her first career of 25 years with AT&T, she served as manager and leader for over 2,000 employees in customer service, sales, marketing, finance, real estate, and architecture. Her final position there as Director of Education offered her the background to establish OakHaven. Her second career took Judy throughout the United States for 14 years as a professional leadership speaker and executive coach for the FranklinCovey Company. Helping organizations and people realize their potential fueled her passion for education and for leaving a legacy.
So, having retired twice, Judy has entered her final career as our Head of School. With her husband Fred and beloved daughter April, she is excited to be living out their family dream to create a peaceful and beautiful educational world for the children.
