About

John Harrington, CFA is the principal of Tandem: RIA Consulting.

John’s 35 years of experience in asset management provides the foundation for constructive partnering with RIAs, and uniquely qualifies him to provide outsourced help to small to mid-sized RIAs seeking growth.

Having deep experience in the critical building blocks of an RIA’s value proposition—portfolio management, manager search and selection, risk analysis, and overall capital markets expertise—constitutes Tandem’s own value proposition.

Prior to Tandem, John headed up client service at the Private Investment Management division of Boston-based LMCG. His day-to-day responsibilities included interfacing with hundreds of advisors and mutual clients, allocation of assets, onboarding new clients as well as acting as internal liaison with LMCG’s operations and trading.

Working with advisors on a wide range of client challenges, and being able to provide them with valuable guidance, provided the impetus for the creation of Tandem. John identified a niche—offering his capabilities on a fractional basis, to midsize or smaller RIAs in investment/operational areas that are typically managed by full time staff at larger RIAs—and in 2024, John left LMCG to establish Tandem.
