We started Nested Numbers because we believe good bookkeeping shouldn’t feel intimidating or out of reach — especially for business owners who are already wearing ten hats. Our goal is simple: give you numbers you can trust and a relationship you can count on, so you can spend less time worrying about your books and more time running your business.

Our Mission

Meet the Team

    Tatiana Welch

    FOUNDER & ACCOUNTANT

    I have a Bachelor’s degree in Business Administration with a focus in Accounting and spent many years working at a CPA firm as a public tax accountant. While I loved the structure and experience that it gave me, I knew I wanted more flexibility — to be there for my kids while still doing work I care about. That’s where Nested Numbers came in.

    I believe in honest communication, dependable work, and creating a balance between life and business that actually feels good. If you’re building a business that supports your family or dreams — I see you, and I’d love to help support you through clear, organized, and reliable accounting that fits your goals.

    Chris Welch

    OPERATIONS MANAGER

    Before Nested Numbers, I spent years managing day-to-day operations — teams, logistics, keeping things running for a large pool and spa company. Now I bring that same steady hand to the business side of our practice, making sure everything works the way it should. 

    I know firsthand how much it takes to run a business — every moving part, every late night, every detail that has to come together. That’s exactly why I want to help business owners like you keep yours running strong.
