About

JSK is an independent registered investment adviser that provides discretionary investment management, financial planning, and consulting to a small client base of individuals, high‑net‑worth individuals, trusts, estates, and small businesses, managing roughly $10.6 million for 12 clients. The firm typically constructs diversified portfolios using low‑cost mutual funds and exchange‑traded funds and will use individual stocks or bonds upon specific client request; JSK does not place client assets into wrap fee programs.

The firm’s investment approach emphasizes long‑term, fundamental analysis and strategic asset allocation with ongoing monitoring and periodic rebalancing, while retaining the flexibility to buy or sell shorter‑term to meet client objectives, tax considerations, or portfolio fit. JSK manages client assets on a discretionary basis, may retain legacy positions when appropriate, and supplements portfolio management with written financial planning or hourly consulting engagements.

Notable differences from many peers include an affiliation with a separate accounting practice: the firm’s principal operates an accounting firm, spends more than half of their time on that business, and may offer accounting services to clients under a separate contract. JSK’s small, concentrated client roster and participation in an institutional custody platform that provides economic benefits to the adviser further distinguish its operating profile from larger independent advisers.

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.
