01 Who We Are
J.S. Lee, principal advisor at Seastone CPA
J.S. Lee, CPA
Principal

J.S. is the firm's principal advisor. A licensed CPA (WA & NJ) and Enrolled Agent, he has practiced on both coasts — at large and midsize firms across public accounting, tax relief, and private equity, and at advisory boutiques serving ultra-high-net-worth families and their businesses. His work spans passthrough structures, real estate strategies, M&A, and cross-border compliance. Offline, he loves being with his wife and son. When not hiking, biking, skiing, or traveling, you'll find him with a small stack of books. His favorite subjects are theology, philosophy, history, and finance.

02 Who We Serve
03 How We Work
Tax Compliance

Compliance is the cornerstone of any sensible tax strategy. For individuals, households, businesses, fiduciaries, and organizations who need their returns prepared timely and accurately.

Tax Strategy & Advisory

Complex operations, cross-border activity, payouts, purchases, big decisions — as the saying goes: early tax advice is especially profitable.

Financial Planning & Analysis

For business owners who want their CPA in the room across the life of the business — operating models, cash flow analysis, scenario planning, and the decisions between.

Goodness of Fit

Successful, long-lasting partnerships require compatibility — you have to like us, and we have to like you. Thankfully, compatibility can also develop with time, and so we welcome the conversation.
