Petroleum Technical Services was started by Keith Tosadori at his kitchen table in November of 1996.  Keith had been servicing and installing fuel systems since 1985 and was ready to do it on his own.  Keith grew his business from his kitchen table to a location on East Jefferson Street in Butler in 2002.  He continued to grow his business with his excellent reputation and industry knowledge.  In 2010 his daughter Kimberly Tosadori- Yerace joined the business and helped her father to continue the growth.  In 2012 the company moved to its current location 1078 New Castle Road in Prospect. Keith had chosen to replace himself with Kimberly as the head of the company in 2017. Kimberly has the knowledge, strength, and Keith’s same determination to grow his legacy.


On January 9th, 2018 Keith lost a long fight with cancer and passed away.  Kimberly and his wife Cheri have proudly taken over the running of business and are excited for the next stages of Petroleum Technical Services growth.
