Everett Koop (former U.S. Surgeon General) was instrumental in setting up the program.  " We provided infants and toddlers born prematurely from Children's Hospital a normal living arrangement in our home until they were well enough to return home to their natural parents".  This experience inspired Mr. Lista to practice medicine and become a Physician's Assistant.  He was a member of the first PA class of Philadelphia University.  He and his wife of 17 years, Judy,  are avid golfers and enjoy spending time with Joe's three adult children and four grandchildren.



A PA is an advanced practice professional ​ who provides the same quality of care as an MD.  What’s different is the level of education between the two medical professionals.  PAs condense much of the same medical school training that doctors receive into a shorter window of time. 

Generally, PAs first receive a four-year undergraduate degree, then go on for at least two more years to receive a master’s degree.  PAs also go through a clinical residency where they spend more than 2,000 hours treating patients in their chosen field. 

PAs must pass board certification and receive licensure to practice, then must re-certify every 10 years.  They must also complete 100 hours of Continuing Medical Education hours every two years in order to renew their Pennsylvania State license.    

Both MDs and PAs undergo extensive training in anatomy, body functions, diseases and treatment.  Both can write medication prescriptions and order lab and imaging studies for patients. 

All chart notes of patient encounters are reviewed by an MD at West Shore Family Practice and an MD is always available, either in person or by phone, for consultation.
