Charissa is the kind of financial professional every organization hopes to have in its corner. She joined our team to provide support during a significant financial transition and quickly became such a trusted partner that, when we needed additional leadership, she seamlessly stepped in as our Fractional Interim CFO.

Charissa is exceptionally smart, practical, and thoughtful, with a rare ability to translate complex financial information into clear, actionable guidance. She doesn’t just manage the numbers; she understands the organization behind them. She takes the time to assess the systems, processes, and people that drive the financial function, anticipates challenges, and helps leaders make better, more informed decisions.

Charissa’s technical expertise, sound judgment, integrity, and sense of humor made her an invaluable partner to our organization during an important period of transition. I would recommend her without hesitation.

"I have collaborated with Charissa for many years on shared client needs, ranging from start-ups to complex, growing $20M+ organizations. Charissa is reliable, highly focused, and efficient. She brings deep technical expertise to nonprofit accounting and has demonstrated mastery on everything from restricted revenue tracking and fund accounting to complex audits, for-profit subsidiaries, and federal negotiated indirect rates. CK Accounting Services is my go-to recommendation for nonprofit clients looking for dependable bookkeeping and strategic financial direction."

I’ve had the privilege of working with Charissa for 16 years through the Angiosarcoma Awareness Foundation, where she has volunteered her time and expertise as our Treasurer. She is extraordinarily mission-driven and selfless, always looking for ways to use her skills to help others and make things better. She brings tremendous care and integrity to everything she does, and she is someone whose judgment I trust implicitly. She’s also a total go-getter. If something needs to get done, Charissa figures out how to make it happen. I feel incredibly lucky to have worked alongside her for so many years.
