Fimple 1

Dr. Jacob Fimple, DDS, MMSc

Dr. Jacob Fimple, an Omaha native, is proud to be part of the Omaha community. He greatly enjoys nature and strives to maintain fitness as an integral part of his life. Outside of the office, most of his time is spent with family.

Through endodontic therapy, Dr. Fimple expresses his desire to provide excellent care to people on a daily basis. In particular, Dr. Fimple finds it most rewarding to offer comfort and relief to patients in pain and to preserve teeth that would otherwise be lost using the most up to date technology. Seeing patients resume their normal life after an infection or serious tooth-ache is very satisfying. Dr. Fimple possesses a natural ability to empathize with patients and he understands the patient’s need for comfort and attention.

This exciting field of dentistry has been blessed with a vast number of recent advances. “I believe it is my duty to incorporate available technology that is proven safe, in an effort to offer the most comfortable and effective treatment to my patients.”

Our office employs digital radiography, which has been shown to reduce the radiation exposure to patients by as much as 90%. Additionally, images are displayed instantly and the need for toxic chemicals is eliminated. What’s more, we have dental operating microscopes which allow for extreme magnification inside the tooth to look for extra canals, cracks, and other factors that could affect the prognosis of the treatment.

Dr. Fimple enjoyed the great experience of serving patients in a private practice setting for three years in the Boston area. Additionally, instructing students at the Harvard School of Dental Medicine as well as currently at Creighton University’s Dental School. This has offered Dr. Fimple the opportunity to contribute knowledge and experience to our future dentists.

Dr. Jason Koh, originally from Houston, TX, is excited to join the community in Omaha where he hopes to learn more about the rich history and vibrant culture abound. He is a self-proclaimed extroverted introvert who is full of energy in the office but, unsurprisingly shy outside of the work environment. He enjoys spending quality time with his wife and two puppies. When time allows, he enjoys photography, the outdoors, reading books, restoring old vehicles, and traveling to explore culture, food, and all the wonderful things earth has to o er.

Dr. Koh earned his DDS degree from the Howard University College of Dentistry in Washington D.C. After graduation, Dr. Koh expanded his dental skill set further in the AEGD program at the UT Health School of Dentistry in Houston, TX where he emphasized his training in restorative dentistry and found an interest in endodontics. In addition to practicing full-time in family practice, he taught at the UT Health School of Dentistry. It was during that time that Dr. Koh then decided to continue his training and pursue his passion of endodontics. He was then able to earn both a Certi cate in Endodontics as well as a Master of Science in Dentistry Degree for his research in bioceramic materials.

Dr. Koh finds joy in being able to provide the best care and chairside manner he possibly can while turning a commonly perceived negative experience into a positive one. He takes pride in the precision required to do endodontics, from being able to understand your concerns, diagnose them properly, all the way to the technical aspects of the treatment itself which allows him to provide relief of pain and discomfort in your ailing tooth.
