Mark K

ChFC®, Series 63

Buffalo, NY

Kostrzewski, Mark Benedict

Mark Kostrzewski is the sole advisor at Kostrzewski, Mark Benedict, holding the ChFC® and Series 63 designations with 30 years of industry experience. He has operated his own advisory practice since 1980. Outside of financial advising, he serves as a managing partner and general partner in oil and natural gas production ventures based in Buffalo, NY. The firm provides advisory referral services primarily to individual clients, including high-net-worth individuals, by referring them to an unaffiliated SEC-registered investment adviser for portfolio management. Kostrzewski evaluates client circumstances to determine the suitability of the referral but does not directly manage client assets or make independent investment recommendations.

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.

Find your advisor

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
