About

Sightline Wealth Advisors LLC is an SEC‑registered, fee‑only advisory firm that provides investment management and financial planning to individuals, high‑net‑worth clients, trusts, estates and businesses. The firm manages approximately $354 million for roughly 290 client relationships and operates as a four‑advisor team.

Sightline’s approach blends passive and active management with strategic asset allocation, diversification and ongoing financial planning, typically beginning client engagements with a written investment policy and planning process. Portfolios are built primarily from ETFs and institutional or no‑load mutual funds, but the firm also uses individual stocks, bonds, covered options and, in certain cases, alternative investments — and it discloses the use of derivatives within separately managed accounts for hedging or tactical purposes.

Compared with many peer team firms, Sightline is notable for employing derivatives (including covered options) in client accounts and for maintaining dedicated operations staff focused on trade execution and money movement. The team includes multiple credentialed professionals (CFP, CFA, CIMA among them), operates under a fiduciary, fee‑only model, and participates on an institutional custodial platform that supplies technology and operational support to the firm.

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.
