Dr. Koester first opened his solo private dermatology practice in 1998. From the start, he has felt that providing the highest quality of dermatologic services was not enough, but that this service must be delivered with patience in a friendly, kind, and caring atmosphere. As the practice grew and thrived, Dr. Koester carefully and prayerfully selected associates to join him in practice, and continues to strive through training and mentoring to ensure that his original vision and expectations continue to be met.
Dr. Koester grew up in Fort Worth, Texas, and completed his undergraduate training at the University of Texas at Arlington. He earned his medical degree from the University of Texas Health Science Center at San Antonio, then completed two years of Internal Medicine Residency at Vanderbilt University. He then completed his Dermatology Residency at the University of New Mexico. He is certified by the American Board of Dermatology and is a member of several professional associations.
He is a strong Christian and relies on the Lord and Greatest Physician to guide his thoughts and give him wisdom to diagnose and treat his patients and relieve their suffering. He strives to live his life both in and out of the office in a manner that clearly reflects his faith. He lives in Edmond with his wife and teenage daughter. He also has two grown daughters.
