About
Sullivan Mermel, Inc. is a fee‑only, holistic financial planning firm that serves individuals and families, including high‑net‑worth and non‑HNW clients. The firm offers comprehensive financial planning and investment management through a standard retainer and an optional premium service, and generally implements trades on a non‑discretionary basis with client approval or a limited power of attorney.
The firm’s investment work is tailored to each client’s tax situation, risk tolerance and cash‑flow needs, drawing on traditional research sources and professional publications. Portfolios emphasize low‑cost no‑load mutual funds, U.S. government bonds and cash equivalents, with allocations managed to address both long‑term growth and short‑term spending needs and reviewed periodically for rebalancing.
What distinguishes Sullivan Mermel from many peers is its retainer‑based fee model rather than charging a percentage of assets under management, and its alignment with fee‑only professional networks (Alliance of Comprehensive Planners, NAPFA, FPA). The firm operates with a small advisory team and provides periodic supplemental client communications and commentary, while maintaining a policy of not accepting commissions or performance‑based compensation.

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
