Dear friends,

Our team has some very exciting news to announce:

Our endodontic practice has moved to a new location!

But don’t worry:

We’re only six blocks away from our original office.

What makes this so special?

Dr. Marshall Lavin moved into the same building as his younger brother, Dr. Mark Lavin… This text opens a new tab to Dr. Mark T. Lavin’s website….

Dr. Mark and Dr. Marshall Lavin

Dr. Mark Lavin is a board-certified periodontist who has owned and operated his periodontal practice in Sioux Falls for more than 15 years!

In the past, their timings never aligned to allow the opportunity to practice together, even though we were only a few blocks apart.


There’s no time like the present, so the dynamic duo is working together at last!

This is such an awesome opportunity, as the two brothers get along very well.

And they have very compatible areas of practice!

Endodontics and periodontics have always been linked together.

Both doctors are concerned with:

  • Relieving your pain
  • Restoring your smile’s integrity
  • Improving your overall oral health and wellness

Endodontists specialize in eliminating infection from your tooth’s root and preserving your healthy tooth structure.

Periodontists specialize in the prevention, diagnosis, and treatment of periodontal (gum) disease and the placement and maintenance of dental implants.

These two dental fields are interconnected because when you’re suffering from a tooth infection or gum disease, the other areas of your mouth are susceptible to becoming infected or damaged too.

By working together, the duo can provide:

  • More accurate diagnosis
  • More efficient treatment
  • Greater results

Now you’ll be able to receive both types of care under one roof. 

Plus, the siblings will be able to get each other’s specialized expertise right then.


You’ll receive expert dental care on another spectacular level!

Where are we located?

You can now find us at 3400 E. 26th St., Sioux Falls, SD 57103… This text opens a new tab to Dr. Marshall Lavin’s Google listing….
