Dr. Sweeten attended dental school in Omaha, Nebraska, at Creighton University. There, he gained a solid education in the fundamentals of modern dentistry. He strongly believes in staying informed about the latest techniques and procedures. Currently, he is enrolled in the John Kois Curriculum, which is one of the country’s leading institutions of advanced post-graduate dental training. Dr. Sweeten loves technology and the advances it can bring to improve the patient experience and outcomes. He works hard to incorporate these advances into the practice as they become available. He looks forward to the opportunity to get to know you and help provide the care you desire, whether that is a more beautiful smile or a healthier mouth.

Dr. Sweeten loves people. He loves meeting and getting to know his patients and their friends and family and being involved in the community.
