About us
Local CPAs who know your numbers by name
Quantro CPA is a 14-person accounting firm on Larkin Avenue. Since 2009 we’ve worked with the restaurants, practices, builders and families of Marlow Springs.
Our story
Started because small clients deserved a real CPA
Sarah Collins spent ten years at a regional firm where small businesses got a junior associate and a once-a-year phone call. In 2009 she opened Quantro with two desks and one rule: every client gets a CPA who knows their business and picks up the phone.
Seventeen years later we’re a team of 14, including five CPAs and two enrolled agents. The rule hasn’t changed. Most of our clients came from a referral, and many have been with us for more than ten years.
How we work
Four promises we keep with every client
Plain answers
No jargon. If you ask what something means, you get a straight answer and, when it matters, a number.
Year-round, not just April
We plan with you before the year ends, check in every quarter and pick up when you call in July.
Flat fees, no surprises
You agree to the price before we start. If the scope changes, we talk about it first.
Your data stays private
Encrypted portal, two-factor sign-in, and we never share your information without written consent.
