Meet Our Friendly Cary Dental Team

Cary dentist, Dr. Darren G. Koch

Chris Hartung - Associate Dentist

Dr. Hartung may be new to our dental office, but his experience in the field covers over 25 years! He loves helping patients from all walks of life achieve healthy, beautiful smiles that are built to last. Dr. Koch and the rest of our team are thrilled to have him onboard. Interested in learning more about him? Just continue reading below, or contact us today to schedule a visit.

Dr. Hartung’s first dental visit as a child was with a pediatric dentist – Dr. Culbreth – who practiced in Charlotte. In a way, that positive visit changed the whole trajectory of his life because it made him want to become a dentist himself, and he never strayed from that goal!

Originally from Rockwell, Dr. Hartung completed his dental doctorate at the UNC Chapel Hill Dental School, graduating in 1996. He has been working hard in private practice ever since. Today, he is an active member of the American Dental Association and North Carolina Dental Society.

Dr. Hartung is the proud parent of two children (a son and a daughter) who are both currently studying dentistry in college! He currently lives on a mini farm in Pittsboro where he raises mini donkeys and goats. He also really enjoys boating in his free time and has completed five half Ironman triathlons in his life.

Kristy, Registered Dental Hygienist

With an impressive 10+ years of experience in the world of dentistry, Kristy joined our team in 2021. For her, the best thing about being a dental hygienist is connecting with others.

Kristy and her husband, Ryan, have two college-aged children and one Golden Retriever, Winnie.

Susanne, Registered Dental Hygienist

Susanne has been working in the dental world for almost three full decades now! She loves getting to know our patients one-on-one throughout their appointment, helping them overcome any fears surrounding the dentist’s office, and improving their dental and overall health in lasting ways.

Susanne studied dental hygiene at Coastal Carolina University. Today, she is also certified in the administration of local anesthesia.

When she isn’t busy at Dr. Koch’s office, Susanne spends plenty of quality time with her husband John, their two sons Jonathan and Brandon, and their three rescue Lab mix puppies.

Their favorite trips so far include stops in the Caribbean, Italy, and Greece!
