Our Story

I (Tammy) started with A-1 Income Tax & Bookkeeping, Inc. in the mid 90’s as a receptionist and preparer support. After encouragement from Lynda and Carole I took the tax class and received my first Oregon License in 2000. I worked in Oregon through tax season of 2004. I moved with my husband and continued to prepare for clients.
Continuously staying in contact with Lynda. In 2016 Lynda called and said she really wants to slow down and retire. I moved back to Oregon in 2017 and purchased part of her clientele in 2020. Changed the name to A-1 Tax & Accounting, LLC.
