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 was referred to see Dr Bell for an emergency root canal. I called them and they got me right in. Excruciating pain, nervous, scared and worried. From the moment I set foot in the offices the staff was absolutely wonderful. Dr Bell was so kind, gentle and explained everything that was going on. Showed me what the problem area was on the xrays, and made sure I understood all that needed to be done, the possibilities that might happen and what to be in store for. Dr Bell and his assistant through the entire procedure were so caring, constantly checking on me. Amazing chairside manner! Dr Bell calmed every bit of anxiety I had. The procedure went so much better than anticipated. After, Dr Bell made sure I was feeling alright and the after care process. I wish Dr Bell was more than an Endo as I would love to be a patient of his more often. More Doctors need to be like Dr Bell. Very down to earth, sense of humor and full of empathy. This is what they do, they see it every day and know...but as a patient, you don't know - all this is new to you and you're scared. They understand this and go above and beyond to make you feel secure. If anyone finds themselves in this unfortunate predicament, I highly suggest Dr Bell.

A couple of weeks ago, I began to experience sharp pains in a older crown. My dentist recommended Dr. Bell to address the problem. His friendly staff was able to get me in quickly and Dr. Bell immediately did a fantastic job of relieving the pain and perform a procedure to solve the problem. Dr. Bell was extremely professional in the way he communicated during the procedure and follow-up! Also, everyone in his support team were very friendly and helpful! If you have any root canal problems, Modern Endodontics is the solution. They are the best!

I can’t thank Dr, Bell and his accommodating staff for helping me when I returned from vacation with a bacterial infection in my gum.  I was referred by my dentist and got the appointment the same day.  I showed up early for the appointment and they assisted me right away.  Dr. Bell was very gently and friendly explaining what he was going to do after taking x-rays in the infection site.  He explains every step of the way answering my questions, he was very patient.  The procedure was quite complicated and the tooth was in a very small area away from my mouth.  When I left I was given instructions of what to expect and to whom to call.  I am now very happy with the results because he was able to save that tooth.  I am no longer in pain and appreciate everyone who helped along the way.  I tell all my friends.

I had the most pleasant experience from Dr. Bell and his assistant. NO pain during or after the root canal. Extremely thorough detailing every step. I actually fell asleep for a moment in the chair I was so relaxed! Highly recommend and will use in the future if needed.

When my dentist told me I needed a root canal, I was fearing the worse. Having the procedure done at Modern Endodontics, I was pleasantly surprised how painless it was and how quickly it was done, thanks to Dr. Logan Bell and his staff. During the procedure, Dr. Bell explained what he was doing along with telling me where he was in the entire process. Comments like we are halfway done, 15 minutes to go, etc. were very helpful. If I needed another root canal or special dental work, I would not hesitate to call Modern Endodontics.

I can't thank Dr. Kasper and his staff enough for the wonderful experience I had at Modern Endodontics. I have always been fearful of going to the dentist and I had to have a root canal. Dr. Kasper explained everything step by step as he went along. He eased my fears and I felt no pain. I was thoroughly impressed with the care, concern, and professionalism I received at the office. Thank you and hats off to a job well done!

I could never imagine raving about a root canal experience, but here I am. The office staff at Modern Endotontics are all kind, friendly and professional. Dr. Bell is just exceptional. He clearly explains everything during every step of the process, and his outgoing, friendly personality made the entire experience a pleasant one. Same with his assistant, Maribel. Don't hesitate to go with this group if the need arises - you won't be sorry.

I had severe tooth pain for days in my upper molar. I wanted the tooth to be extracted just to get me out of my misery. Dr. Bell was able to get me in quickly to take a look. He gave me options on how to proceed to SAVE the tooth. He was very knowledgeable in explaining the process of what he was doing during the procedure which was quite relaxing. I had very minimal pain the next day. I would highly recommend him if you have severe tooth pain.

I saw Dr. Bell for a root canal on one of my front teeth. I was understandably nervous.."It's my front teeth!". Dr. and his staff put me at ease right away. Dr. Bell spent the time to explain what was going to happen, and let me know what to expect before each step. I have had good root canals before, but this was Pain Free !
