Ali Williams
Ali Williams, CPA

I have three young kids and love the crazy life of a working mom and business owner! Although I'm not a Yakima native, I've grown to love the Yakima Valley and enjoy spending time in the beautiful landscape that surrounds us.

I graduated from Central Washington University with a Master's degree in Processional Accountancy. I hold memberships in the American Institute of Certified Public Accountants and the Washington Society of Certified Public Accountants as well as serve on the board for the local Yakima WSCPA chapter.
