Ronald Goldenberg, DMD

Has been in dental practice since graduating from the School of Dental Medicine at the University of Pennsylvania in 1975. He did his hospital residency at the Philadelphia General Hospital in 1976 and received his Bachelor of Arts in Science from Temple University in 1971. In addition to clinical practice, Dr. Goldenberg teaches clinical restorative dentistry at the University of Pennsylvania.

He has been honored as a Top Dentist, as selected by his peers, by Main Line Magazine several times since 2001 in the categories of General Dentistry, Cosmetic Dentistry, and Implant Dentistry. Dr. Goldenberg’s peers also elected him President of the Dental Society of Chester County and Delaware County in 1992 and he served as Chairman of the Valley Forge Dental Conference in 1993. He was inducted into The International College of Dentists in 1995 and is a member of the American Dental Association, the Pennsylvania Dental Association, and the Dental Society of Chester County and Delaware County.

Dr. Goldenberg is a resident of the center city since 2006 and is excited to be associated with Walnut Street Smiles after having practiced in Delaware County for over 30 years.

He is an avid golfer and enjoys traveling with his wife, Susan. They are the proud parents of three daughters and grandparents of six.

Jonathan Volinsky, DMD

Born in Philadelphia, Dr. Volinsky attended the University of Rochester from which he graduated with honors in two major disciplines and then received his dental degree from The University of Pennsylvania. Immediately following graduation, he was appointed Clinical Associate in the Department of Restorative Dentistry at Penn and both lectured and instructed students at the clinical level. In 1984, Dr. Volinsky received the distinct honor of being awarded both clinical teaching prizes given by the student body, in recognition of his skills as an instructor as well as his devotion to the welfare of his students. 

Dr. Volinsky has managed successfully nearly every dental problem which a patient can present. He was, due to his academic standing as well as his natural inquisitiveness, present at the very beginnings of what became the foundation of modern restorative dentistry. He was among the first in Philadelphia to institute specific innovative techniques of restoring patients’ ability to function properly and efficiently as well as to dramatically improve their smile, treatment modalities which are now universally applied.  He was and is known and respected for his unceasing devotion to the health and welfare of his patients, each of whom he treats as individuals, recognizing the specific needs of each person with respect to dental needs as well as personal preferences and desires. This humanistic and altruistic approach served his practice for forty years and he has become a known fixture in the “neighborhood”, always willing to go the extra mile for his patients. He very much looks forward to providing this classical form of healthcare for many years to come.
