About

Abacus Financial Planning is a small, advisor‑led firm that serves individual and high‑net‑worth clients with discretionary investment management and comprehensive financial planning. The firm reports roughly $6.0 million in discretionary assets under management and provides continuous portfolio supervision alongside written or electronic financial plans for clients.

The firm’s investment approach is grounded in Modern Portfolio Theory and strategic asset allocation, relying primarily on passive mutual funds and exchange‑traded funds for long‑term, tax‑aware portfolios. AFP integrates financial planning into its investment management work and will advise on legacy or concentrated positions, including option strategies such as puts or collars when appropriate.

Several operational and personnel features distinguish AFP from many peers: its advisory team includes principals with doctoral‑level academic backgrounds alongside CFP® credentials, and the firm emphasizes an integrated planner‑led relationship rather than treating planning as an optional add‑on. AFP also relies on a single, recommended custodian (Schwab), does not aggregate client trades into block orders, and does not provide separate written investment reports to managed‑account clients, instead relying on custodian statements for account activity.

Katy C

CFP®

Kirkland, WA

Abacus Financial Planning

Katy Cook is a Principal at Abacus Financial Planning and decided to change careers and go into financial planning after creating her parents’ retirement plan. She saw firsthand the peace of mind that comes with having a roadmap to guide investing and spending decisions. She has also seen how that plan can be tested with health concerns and a global pandemic. Katy helps women, their families, and anyone historically underserved by the financial industry use money to live the life they want. She enjoys helping people explore financial scenarios and understand the long-term impact of small (and large) choices. Prior to being a financial planner, Katy spent a decade in teaching and independent consulting focused on “data for do-gooders.” She completed a BS in Mathematics at the University of Texas at Austin and a financial planning certificate with Boston University. She holds a Ph.D. in Applied Mathematics from Princeton University, where she was a National Science Foundation Graduate Research Fellow. While teaching, Katy gravitated to the “guide on the side” model of teaching, rather than the “sage on the stage” model. This is a great fit in financial planning, where Katy provides gentle support on the side. She continues to teach finance and business classes at Southern New Hampshire University. Katy volunteers with non-profit organizations that support children, family health, and education through board and committee work. She previously served in AmeriCorps offering financial support services for people with low income or developmental disabilities. She serves as a volunteer tax preparer, though you can’t pay her enough money to do your taxes. Katy loves living in the Pacific Northwest. On clear nights, you’ll find her in the backyard with a telescope and her dog by her side. Sometimes her multigenerational family joins her outside, too.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.

Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.

For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
