Katherine J Pendergraft
Assistant Coach - Edmond
Email
With ten years of athlete experience including being an Oklahoma All State swimmer, Katherine considers herself a self-taught sprinter with a deep love of the sport. Having swam briefly under the guidance of Dr. Sam Freas and accepted his mentorship off the pool deck; she understands the need for a holistic approach to the sport. She encourages discussion during challenges and trying solutions that may be outside the norm as she is an unconventional student herself. She believes in unlocking the abilities of individuals and inspiring them to see the best in themselves, their work, and the people in their lives. Away from the pool, she enjoys being an active part of her church by being a part of the church choir and teaching Sunday school.
