Dr. Charlotte Senseny DDS

Charlotte Senseny


Dr. Charlotte Senseny grew up in Chambersburg, PA, a small town not far from Gettysburg and Harrisburg. The town lies in a narrow valley affording the area with many outdoor activities. The mild weather and four nearly equal seasons provided for rich farmland and many orchards. Charlotte enjoyed biking, swimming, and tennis growing up and participated on the swim and tennis teams in high school. She followed her older brothers into the city and the harsher winters as a student at the University of Pittsburgh. There she majored in Chemistry and graduated summa cum laude and was recognized as a University Scholar. From Pitt, she travelled to a larger city and even more harsh winters to attend Harvard School of Dental Medicine in Boston. There while studying hard, Charlotte met her husband to be, James Callahan and both of them graduated magna cum laude. As encouraged by the dental School, both Jim and Charlotte took the opportunity to pursue a General Practice Residency and they ended up in yet a larger city, Los Angeles. After completing the general practice residency at the West Los Angeles VA Medical Center, Dr. Senseny continued to complete a residency and certificate in Advanced Prosthodontics. After three years of beautiful weather and warm winters, the couple decided to settle in here in the South Bay. Dr. Senseny served as an assistant clinical professor at USC while building her practice. When her daughter, Meagan, arrived on the scene, Dr. Senseny changed her focus to dentist and mother. Over the last thirty years of practice, Dr. Senseny has continued to study and increase the scope of her practice. She has also been active in advancing the profession of dentistry through participating in her local dental society, the Western Los Angeles Dental Society and through a wide breadth of appointments in the California and American Dental Societies. Dr. Senseny can be seen in the balmy CA weather riding her bike to work.
