Dr. Mbinglo is the most passionate CPA I’ve ever met. She loves what she does and it comes through in how she shares her knowledge with and genuinely cares for others. If I had a business, The Ark would be my accounting firm.

FAQ
Frequently Asked Questions
Common questions about our tax, accounting, and nonprofit services.
What services do you offer for small businesses?
We provide tax preparation, bookkeeping and accounting, business registration (LLC, S-Corp, C-Corp), tax planning and strategy, and business partnership consulting. We work with businesses of all sizes to keep your finances organized and tax-compliant.
Do you work with nonprofits and churches?
Yes! Nonprofit services are one of our specialties. We offer nonprofit startup and registration, tax preparation (Form 990), bookkeeping, and financial statement audits and reviews for organizations that need them.
What's the difference between an audit, review, and compilation?
An audit provides the highest level of assurance with full verification of your financials. A review offers limited assurance through analytical procedures. A compilation organizes your financial data into statements without assurance. We help you determine which service your organization needs.
