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.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
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. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
