With her recent nuptials and legally changed name, Dr. Seifert has decided to rebrand her practice as Maple City Dentistry beginning in 2018. The new name and brand reflect the practice’s commitment to continue to grow and better serve the oral health care needs of its patients.

Outside the office, Dr. Seifert is committed to community service and dedicates her time to various organizations including Big Comedy LaPorte and the LaPorte County Family YMCA. In her free time she loves spending her time cooking in her kitchen or running, biking and hiking outdoors with her husband Jason and two stepsons.
