Our Office

Welcome to our practice. Our specialty dental practice is dedicated to treating patients who need root canals, root canal re-treatments, and apico surgeries. Our office is conveniently located in the city of Sioux Falls.

We follow a strict and modern sterilization protocol which fully utilizes state of the art equipment and sterilization techniques. Our sterilization system surpasses OSHA requirements. Unlike most dental offices who use tap water, our office exclusively uses distilled (purified) water in our dental units which removes any chance of contamination. Our friendly and competent staff is dedicated to patient comfort and quality of care.

We make sure that our patients are being provided the most current treatment options and cutting-edge dental technology available.

We look forward to welcoming you to our specialty practice.


We accept most insurance plans. We also accept payment from most PPO and indemnity plans. Please call our office to make an appointment and we will answer any questions you may have.

Payment Options

We accept all major credit cards, cash, and personal checks. For our patients' convenience we have arranged a payment plan through a third party, which helps our patients receive their treatment in a timely manner.
