    Dr. Andrew R. Bruening

    Dr. Andrew R. Bruening is the owner of Chesterfield Hilltown Dental, the office that his uncle founded in 1989. He remembers shadowing his aunt and uncle as a teenager when he decided he wanted to be a dentist. He is from St. Charles, MO and joined his uncle in practice back in May 2014. Dr. Bruening studied Food Science & Nutrition at the University of Missouri - Columbia before graduating with honors from University of Missouri Kansas City School of Dentistry. The Iowa Dental Association named Dr. Bruening an honor clinician at their regional dental conference, and the Midwest Dental Conference awarded him 3rd place for table clinic presentations. In 2013, he traveled to Uganda for a dental mission trip and is planning to do future work in Africa, South America, and Thailand.

    Dr. Bruening has always had a love for art and science, considering himself a true “nerd”, feels that being a dentist allows him to combine both of those appreciations into a career. His favorite part of being a Dentist is changing/making a positive impact on someone's life. Getting someone out of pain or giving someone a smile they can show off, is extremely rewarding for him.

    Outside of the office, Dr. Bruening enjoys traveling, photography, reading, cooking, brewing beer, playing golf, and spending time with his wife. He likes to read a lot of dental related things, and is an avid reader in general. He is an alumnus of Psi Omega dental fraternity and is currently working towards a Fellowship with the Academy of General Dentistry.

When Carissa was 15, the dentist in her hometown asked her to work in his office over the summer. That experience sparked her interest in the career and she has loved dentistry ever since. When asked her favorite part of dentistry, she explained that she loves the patient interaction and meeting new people. She also feels great pride in restoring a smile and healing pain.

    Dr. Carissa genuinely enjoys the education side of dentistry.
