What Long Lake Capital Management, LLC does

Long Lake Capital Management, LLC is a boutique, fee-only Registered Investment Advisor founded in 2014 and headquartered in Birmingham, Michigan. The firm designs and manages customized investment portfolios for individual clients, families, trusts, estates, and other entities, with a stated minimum of $500,000 in total household assets. Portfolios are constructed primarily from publicly traded equities and individual fixed income securities; the firm explicitly avoids mutual funds and other products with embedded fees, and clients are billed under a recurring (annual) advisory fee structure on a fiduciary basis.

The firm employs a value-focused, bottom-up research process designed to identify dislocations between a company's intrinsic value and its current market price, with a 3–5 year investment horizon and the S&P 500 as its performance benchmark. Client accounts are custodied at Charles Schwab through a dedicated client login portal, and the firm maintains a single physical office at 401 S. Old Woodward Ave., Suite 435, Birmingham, MI 48009, with a Twitter presence (@LongLakeCapital) and a website contact portal. President Bryan Mortenson leads the firm and brings 15+ years of experience from prior roles including Senior Equity Analyst and Portfolio Manager at R.H. Bluestein & Company, and he holds an MBA from the University of Michigan's Ross School of Business.

The firm is structured as a Michigan LLC, is registered as an investment adviser with the state of Michigan, and only conducts business in states where it is properly registered or exempt. No revenue, AUM, employee count, or ownership data is publicly disclosed. A separate or affiliated entity identified as "Long Lake Management" is associated with a May 2026 agreement to acquire American Express Global Business Travel for $6.3 billion; that transaction's relationship to the RIA entity is not clarified in the source material.
