Staff Profiles

Jeri Beth Dettinger, EA:

Jeri is the founder of J-tax-S. Jeri is also an Enrolled Agent(EA). She passed her EA exam in 2004. She is a member of NAEA, NATP and PSEA. Prior to earning her EA so worked for a national tax firm for 5 years. After becoming an EA she worked for two years for a CPA. She then decided it was time to start her own business which had been her dream all along. She just wanted to make sure she had enough experience to offer quality services.

Growing up in Dallastown, both Jeri’s father and grandfather owned businesses where she got hands-on experience learning bookkeeping, customer service, and how to run a successful business. Before starting J-tax-S, Jeri continued learning and advancing herself through different jobs. Overall, she worked as a bookkeeper for several businesses and did payroll for several other companies. Over the years, Jeri has accumulated firsthand knowledge in small business areas such as construction, auto sales & repair, small retail specialty stores (IE- craft, musical instruments, appliances, carpeting, etc), direct sales, and service businesses. This wealth of knowledge proves to be an invaluable resource to many who need advice on record keeping, business planning and structure, etc.

Since starting in 2005, Jeri has had to add several more staff members in order to better serve clients. Everyone still reports back to Jeri and she reviews the returns prior to them leaving the office.

Amber Stephens:

Amber joined our staff in November of 2018 and has been a great asset to our business.   Amber comes to us with a degree in accounting.   She is a Quickbooks expert and experienced payroll clerk.   She worked for a local CPA for over 6 years until he had to retire for health reasons.   She then went on to work for another CPA firm before joining us here at J-tax-S.   She has been doing the bookkeeping for our clients and is taking on many responsibilities here at the office. She is also an experienced tax preparer and will be helping with tax preparation this year.  Adding Amber to our staff has provided our clients with a wealth of expertise in areas that Jeri wasn’t as familiar with.

Caity is Jeri’s daughter, she grew up in the office while being homeschooled.   Many of our clients have seen her grow up and are excited to see her each tax season.  In 2012 she became the office manager.  She also helps with data entry and receptionist duties as needed.   Currently she is working on becoming a Notary to help with the DMV work here at the office.   She is actively involved in community theater at Theatre Arts for Everyone (TAFE) and DreamWrights,  so you may see her in performances at either of these theatres from time to time, although she is mostly involved  behind the scenes.
