Meet the Staff

Kathy Mueller

Kathy Welcome! I am a dental hygienist and have been with this practice for more than 12 years! The doctors here are all fun and easy to work with, and they truly care about our patients. My favorite part of my job is when a patient tells me that their mouth feels great at the end of a visit! I have been married for 19 years and have two children. My son is 13 years old, and my daughter is ten. We also have lots of pets, including dogs, cats, rabbits, horses and chickens!

Lea Ann Smith

Lea Ann I have been a dental hygienist for 20 years and have been with this practice for 14. Seven of those years have been part time since my kids came along! I am often the first team member to have contact with the patient, and I know how important it is to make their first visit a good one! My favorite part of my job is meeting all of the different types of people that come in to our practice. At home, I have been married for 14 years, and my husband and I have two children, aged seven and three.

Lora Haas

Lora I’m a dental hygienist, and I have been with the practice for 11 years. I enjoy getting to know our patients and interact with them with a calming nature and a gentle hand. I love working with people and helping them live healthier lives. In my spare time, I enjoy outdoor activities such as boating and motorcycle riding! I’m also a huge sports fan and especially love the St. Louis Cardinals! Most of all, I enjoy spending time with family and friends.

I graduated from Kaskaskia College in 2003 with an Associate Degree in Arts and a dental assisting certificate, then from Lake Land College in 2005 with an Associate Degree in Science. At home, I am married and have two young sons.

I graduated from Missouri College in 2004 with academic honors, and am now a chairside assistant with expanded duties in sealants and coronal polishing. I also cover a variety of administrative duties. My favorite part of my job is when our patients turn to the doctor and me, and tell us how grateful they are for our gentle treatment!

I also verify insurance benefits for our patients, and make sure they receive the most from their coverage. My family consists of my loving husband, our four children and seven beautiful grandchildren! I also can’t forget our black lab, Abbey!
