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 cannot tell you how afraid I was to find out that a root canal had to be re-done, but my dentist knew exactly where to send me-to Dr. Kaspar! He is amazing. So calm and caring about his patients, he explains everything, answers all your questions and nothing fazes him. The staff in the office is amazing, so polite and professional they put you at ease immediately. I am not done with my procedure yet but they make going there a very positive experience. Thanks to you ALL!

Dr. Kasper was so professional. I have to say I have always hated going through any dental procedures but when I went for my root canal and when I left from my first appointment and procedure I was thinking they should call it something other than root canal, as it wasn't as horrible as I was expecting or sounds. I would recommend them to anyone, also the assistant was great.


I walked to Dr. Kasper’s chair quite fearful and in a lot of obvious pain. He has a wonderful calming manner, explained what he was planning to do and throughout the procedure kept me informed. I can truly say it was a good experience.Thank you so much Dr. Kasper.

Dr. Bell and the staff at Modern Endodontics are wonderful.I took in my 7 year old for a somewhat urgent procedure and they took us in right away and even tried to get us in before our scheduled day.The staff is friendly, polite and professional. Dr Bell is amazing. Not only did he explain the procedure in detail to me he also put my daughter at ease by telling her what he was going to do without traumatizing her.She was actually looking forward to her 2nd appointment(2 step process) .I highly recommend Dr. Bell and his staff at Modern Endodontics.

Working with Dr. Bell was an absolute pleasure. I was in extreme pain and found out that I required a root canal. This was my first experience having this procedure done and Dr. Bell thoroughly walked me through the process as well as answered any questions I had. My apprehension and anxiety were immediately put at ease. I would highly recommend him and his staff, they are by far one of the most professional offices I have ever visited.

No one looks forward to a root canal but the procedure was done by Dr. Kasper seamlessly. He was very reassuring and explained the entire process. Also the staff at Modern Endodontics were very friendly and helpful with insurance.

Dr. Kasper has a very calming manner and he and his staff and the facility and equipment are all top notch. I would highly recommend this practice when you need help with a root canal. The worst part of having a root canal is largely the anxiety prior to the visit. Once you get there you are instantly put as ease by the staff. Great care is taken to assure a very comfortable experience is what you have. Dr. Kasper is also very thorough in his procedure and in explaining things. Very, very positive experience.

Dr. Bell is amazing. My first visit was on an emergency basis. He and his staff were so caring and very professional. The treatment was painless! My second visit was also painless. Each time I was given patient information and the staff followed up the next day. I recommend Dr. Bell highly. He has a wonderful warm manner and will take care of you!

I would never have imagined writing a positive testimonial about a root canal, yet here I am. Dr. Bell saw me on a semi-emergency basis on a Saturday and performed the first step of the two step process. He completed step two this week. Never have I been as impressed by anyone in the medical field as I am with Dr. Bell. His "chair side" manner is great, his coordination with his assistant is impressive and I experienced absolutely no pain. I hope I never have to have another root canal, but if I do, I'm going to Dr. Bell. BTW, the background music in the office is awesome also!

The office staff was superb. They were polite and would call if there was a cancellation so I could be worked in. I had never had a root canal and had heard so many scary stories. My experience went without a hitch. NO PAIN! Very relaxing atmosphere and they talked to me throughout the procedure. My comfort was their primary concern. I hope I never need another procedure, but if I do, I will come back to the office without hesitation!
