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 and PSEA. Prior to earning her EA so worked for a national tax firm for 5 years and 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, 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 ALL returns prior to them leaving the office.

Caity is Jeri’s daughter, she grew up in the office as a homeschooled child.   Many of our clients have seen her grow up and are excited to see her each tax season. Over the years she has taken on more responsibilities.  For the past 5 years she has been the office manager and receptionist. The past two years she has been helping with tax preparation.   Even though Jeri would love to have Caity takeover the business someday when she retires, Caity has stated that this business and taxes aren’t a part of her dreams for a future career, so for now we will enjoy having her here. Her dreams right now are at the theater and she is actively involved at DreamWrights and helping with a new theatre in the York area call TAFE (Theatre Arts for Everyone), so you may see her in performances there from time to time.
