Thank you for selecting the endodontic office of Dr. Edward L. Kasper and Dr. Logan T. Bell.  We are an endodontic specialty practice dedicated to exceptional care using state-of-the-art technology.


Our Mission is simple: to provide you with the finest endodontic treatment available anywhere, in a pleasant and courteous atmosphere.


Our "make no compromises" philosophy allows us to treat patients to the utmost of our abilities in a way that will lead to a pleasant experience for you.  This is a tall order but we feel that taking time with our patients and being open to their needs is of the utmost importance.

With our new office we have made sure to provide our patients with the most up to date techniques and cutting edge technology so they receive the best quality care in the most comfortable environment.

Practice Profile

Our office is known for its commitment to excellence.  We use the latest technology including the surgical operating microscope which offers increased magnification and illumination for all procedures.  Whether we are evaluating the outside surface of a tooth for a crack, locating miniscule root canals, removing a broken file from a root canal, ensuring the canals are thoroughly cleaned, or filling the root canal systems, the microscope benefits treatment.   Even the smallest detail is brought clearly into view.  We also replaced conventional dental x-rays with digital radiography. This advancement significantly reduces radiation exposure to our patients and eliminates the hazardous byproducts of film developing.

Always on the forefront of technological innovation, we have converted to digital record keeping and use of the Internet for the convenience of our patients and referring doctors.  For example, we encourage you to pre-register at this web site to save you time when you come to our office for your appointment.  It is simple to use.  Please call our office for instructions.


Together, our commitment to you is that you receive the best care that is possible today.

I have always been uncomfortable with any dental care due to several bad experiences in childhood. But I have to say, this was the most relaxed and comfortable I have ever been in a dentist's chair! I was referred from my regular dentist for an emergency root canal, and the Modern Endodontics staff are just wonderfully friendly and helpful. Dr. Kaspar took great care to ensure I felt no pain during my visits, provided details about what he was going to do and what was happening while he was working on my tooth. Seriously the best dental experience I have ever had — HIGHLY recommend this office and these people!!

I was referred to Modern Endodontics by my dentist to investigate severe pain. I met with Dr. Bell and he was simply terrific. After testing me and seeing me in pain, he fit me in later that same afternoon for a root canal. The whole process was excellent - Dr. Bell and his assistant did a fantastic (and painless) job. My follow up visit with Dr. Bell was equally good - in 60-75 minutes, he inspected, and finalized the root canal treatment. I could not be happier and have already told my friends to reach out and meet Dr. Bell should the need arise. To be sure, Dr. Bell's assistants during the procedures and the office staff are terrific as well. Do not look anywhere else!


I was completely satisfied with the care I received at Modern Endodontics. Including Dr.Bell, his assistants, and the staff at the front desk, I interacted with seven or eight members of the staff. Every single one of them was pleasant, courteous, and enthusiastic, and conveyed genuine interest in ensuring that I received the best possible care. This was absolutely the most positive medical experience I have ever had! I would recommend them anyone.

Dr Bell was very thorough  and took the time to explain everything that was going to happen. I was always comfortable. I would definitely come back to this office if needed again.

I am very happy with the decision to have redone my root canal by Dr Kasper.I did not know anything about him before my regular dentist referred me to him, but, with what I know now, if I or member of my family need endodontist in the future, we would not look for another doctor. From the beginning, Dr Kasper provided me with detailed explanation of the problem with a tooth, his approach to resolving the problem and a prognosis. After receiving my agreement, Dr Kasper successfully completed his plan with a great efficiency. I also must note that the staff of this office cannot be better! Thank you to all!

IF a root canal can be a pleasant experience this is where it is made! The patient was actually my wife who suffers from Alzheimer's. From walking in the door the office is friendly, knowledgeable and caring. They even remember personal conversations from prior visits. The Dr. has a wonderful 'patient side' manner, very caring, and a master at his craft. Follow up to see how she is doing, and a follow up check up advised in a year. Would not go anywhere else and would actually travel to come back here if there's a future need (please no!).

Dr. Kasper was great and made me feel comfortable. The staff are pleasant and friendly. Well run office


If you need a root canal this is the place to go. I was very satisfied with the care I received and Dr. Kasper and his staff were the best.


I am such a nervous Nelly about dental procedures! Dr. Bell as gently as possible got me part way thru part 1 when we both decided a mild sedative was needed. I came back for parts 2 and 3 and was able to sit still in comfort. I also have to mention how kind and curteous the front desk and tech staff were. Thanks Dr. Bell and team!

Although going to the dentist for anything, a root canal is my worst fear. Those fears were quickly dispelled by Dr. Kasper and his staff. He explained everything and his skills are amazing. As painless as could be!
