Insurance Coordinator (Dental)

Holli is Summer Smiles insurance coordinator.  She fights and battles with insurance company on a regular basis, and be glad that she is on your team.  

Holli is our other red head in the front office.  We somehow recruited Brittany’s mini me and are now stuck with two red heads full of energy, life, and fire.   Prior to dental, Holli worked in the childcare industry for 8 years and happened to teach Dr. Hsia’s son while he was in her class.  Dr. Hsia recruited Holli after seeing the spark in her eyes when she engaged her students, her genuineness, and how invested she was in every child.  He knew then, that she would be perfect fit for Summer Smiles.

Outside of work, Holli is terrified of feet and is obsessed with babies.  She has two beautiful littles ones, named Colt and Lilah.  She is an Allen native and a new home owner in Princenton.
