Summer Kim – Practice Manager

Summer is the practice manager and John’s wife. She has been working with John since 2010. She started out as an Orthodontic Assistant for 5 years and then met John in 2007.  They were married in 2009 and had their first daughter. It was then that she made the decision to leave orthodontics and come manage the practice. Their daughter Ava was very much a part of the practice in the beginning as well. For a year she was here with them twice a week and the patients have watched her grow up.

Summer says “I have not only seen our office grow but our patients and their families as well. What I enjoy most is making them a part of our family. We have an awesome staff and take pride in fulfilling our patient’s dental needs. John is a caring person and excellent at what he does, he makes our patients feel comfortable and makes people SMILE.”

Summer enjoys spending her time outside of work with their two children Ava and Ryan and their dog Brie.  She tries to get in some family time any chance she gets!
