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.

Dr. Kasper did my root canal and it was totally painless. He was friendly and professional and he explained the whole procedure to me. His office staff and assistants were extremely nice and friendly. I would highly recommend Dr. Kasper for anyone needing his expertise.

I am admittedly one of those who fear dental work to the point where just the thought of it creates terrible anxiety. Dr. Kasper and his staff treated me so well and assured me that I would not feel any pain on my initial root canal visit. In fact I felt absolutely no pain during the procedure. When I went back for the second treatment for the root canal I was as calm as sitting in a library. No anxiety or fear this time. While I hope to never see Dr. Kasper again, if I need dental work in the future this is where I am going to go.

I normally don’t write testimonials however, what I continue to experience with Dr. Logan Bell and his staff is a story to be told. Dr. Logan Bell puts you at ease instantly, educates you from beginning to end, provides all your options accordingly and answers all your questions. When the procedure is taking place you know exactly what to expect. And it doesn’t stop there, the extraordinary service continues on with his staff which makes you feel welcomed with each and every visit. I’ve had my share of dentists (endodonctic) over the years, however, no one to this date has exceeded my expectations like Dr. Logan Bell! Cheers to Dr. Logan Bell and his staff for their service and dedication to this practice. I HIGHLY recommend Dr. Logan Bell over and over again without reservation and his staff at Modern Endodontics—-you will NOT disappointed with the treatment or the experience!

Just finished the final step of my root canal with Dr. Bell today. I feel wonderful. He explained everything every step of the way and put me at ease. If I have any friends or family who ever need a root canal I will definitely refer them to this office!

I have literally never left a review of anything or anyone on the internet but I thought I should to help others like me. I am a GIANT GROWN WOMAN BABY about dental work. Straight-up phobia. So when I had to get a root canal - thud. My dentist assured me these guys were the best. She was not kidding. Dr. Bell and his assistant were so nice, calming, discussing everything that was going to happen and so utterly patient with my nonsense. And here's the thing - I really never felt a thing. It was unbelievable. I can't recommend them enough.

Oh my gosh, I am so very happy my dentist recommended me to see the doctors at Modern Endodontics! Doctor Kasper was SO PATIENT and understanding. He was very conservative and took his time figuring out which tooth was actually causing the problem. He explained what he was doing every step of the way and took his time and showed the x-rays, etc. His staff from the front desk to his assistants were ALL kind, polite and professional. I will recommend Doctor Kasper any chance I get. Thank you to everyone!

5 star rating to Dr. Bell and his staff. If you need a root canal,there is no need to be anxious or scared with Dr. Bell doing the procedure. Totally pain free during and after the procedure. If ever the need arises for further treatment, without hesitation I would choose Dr. Bell.

I am very pleased with services that I from Dr. Bell and staff. I was seen promptly. His staff was very friendly and accommodating. Most importantly, Dr. Bell performed my root canal perfectly. He was reassuring throughout the procedures, initial and follow up explaining everything as he went along. He uses state of the art equipment, including microscopy to examine the tooth for cracks. I highly recommend Dr. Bell and his staff at Modern Endodontics.

I recently had a root canal performed by Dr. Bell. I found Dr. Bell and his staff to be very professional in handling my matter and would recommend him to my family and friends if they are in need of endodonctic services
