We started Nested Numbers because we believe good bookkeeping shouldn’t feel intimidating or out of reach — especially for small 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

Tatiana Welch

Hey there! I’m Tatiana— a former tax accountant, and most importantly, a stay-at-home mom to two sweet girls who keep me busy and full of purpose every day.

I have a Bachelor’s degree in Business Administration and Accounting and spent 8 years working in 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.

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.
