Dr. Rob D. Lyons, D.D.S.


  Dr. Rob Lyons was born and raised in Buffalo, South Dakota where he graduated high school in 2002.  He was convinced that dentistry was in his future after shadowing his local dentist throughout his senior year.  He began his undergraduate studies at South Dakota State University and graduated in 2006 with a Biology/Pre Dental major and a Chemistry minor.  He took a year off between undergrad and dental school to teach and coach at Harding County High School.  The following year he began dental school at Creighton University in Omaha, NE and graduated in May of 2011.

Upon graduation from the renowned Creighton University School of Dentistry, Dr. Lyons was presented the Department of General Dentistry Award.  This award recongnized a graduating dentist that has demonstrated outstanding clinical skills and a gentle/caring professional approach to patient care.  He does everything to continue this character description in his every day practice.

Dr. Lyons decided that the small town values of Western South Dakota are where his heart lies and decided to return following graduation.  He has practiced dentistry in the Black Hills since 2011 and is excited to continue to serve Rapid City and the surrounding areas at Ponderosa Smiles!

Dr. Lyons and his wife Amber have one beautiful daughter, Kahlia and a strapping young son, Huxley.  They are the highlight of his life and, as patients know, he talks about them constantly!  When he is not practicing dentistry Dr. Rob and his family are outside enjoying all the outdoor opportunities that South Dakota has to offer.  During the summer, they can be found camping and fly fishing throughout the Black Hills, hiking Black Elk Peak, or taking care of their garden.   On weekends throughout the fall they are usually following around their German Shorthair Pointer, Jager, hunting pheasant and grouse.  During the winter, they enjoy time with family and ice fishing.
