History of the Practice

After completing a pediatric dental residency at Children's Hospital of Pittsburgh, Dr. Peter J. Ross settled in Lancaster, PA, based on the advice of college friends Tom and Joanne Ladley.  He started a pediatric dental practice at 1875 Lititz Pike on August 26, 1985.

It was a small office, approximately 750 square feet, with a reception area, receptionist's desk, and three treatment rooms.  Since Dr. Ross had a limited budget, only two rooms had dental chairs and units.  His wife, Louise, was the receptionist and book keeper.  Dianne Newcomer, a dental assistant, was the first employee hired before the office opened.  She was interviewed in Dr. Ross's home.  Beverly Miller Rogers was the first dental hygienist hired in 1986.  Kay Hudak was the first receptionist hired in 1987.

After a slow, but steady start, the practice began to grow.  The office space was expanded three times from two equipped dental rooms to eleven.  The office space was expanded on three occasions to its current 7100 square feet, completed in 2007.

There have been many dentists who practiced at Lancaster Pediatric Dental Associates (LPDA).  Dr. David F. Laughlin was the first pediatric dentist hired, practicing part-time while starting his own private practice in York, PA.  Dr. Patricia Alvarez practiced full time until she moved on to start her own practice in Mountville, PA.  Dr. Erik Schiefele came from his dental residency in Denver, Colorado to work for three years before getting the teaching bug.  He is currently the program director for the pediatric dental residency at Children's National Medical Center in Washington, DC.  Dr. Elizabeth Harrison practiced for seven years at LPDA, commuting from Mechanicsburg, PA, every day until she found a practice closer to her home.

Dr. Kimberly Coblentz, graduating from her pediatric dental residency at Texas A&M University-Baylor College of Dentistry, joined the practice in July, 2001.  She was a former patient of Dr. Ross, worked summers in various positions within LPDA, while attending Penn State, and matriculated to Temple University School of Dentistry, graduating in 1999 at the top of her class.

Dr. Ying-Lee Ong graduated from Temple University School of Dentistry in 2010, claiming to have had Dr. Ross as a clinical instructor in the pediatric department.  After completing her pediatric dental residency at Children's Hospital of Pittsburgh, she joined the practice in 2012.

Dr. Brainne Shanley, a 2010 graduate of the University of Pennsylvania School of Dentistry, joined the practice after completing her pediatric dental residency in 2012 from St. Christopher's Hospital for Children in Philadelphia, PA.
