Best M&A Advisors in San Diego: 8 Firms Ranked (2026)

Objective Investment Banking & Valuation, Sugar Tree Capital and Fleetridge Pacific lead this guide because each states 100 or more completed transactions on its own site. LR Tullius, Corporate Finance Associates and Schwartz Advisors follow with a San Diego-area office and an M&A focus but no firm-wide deal count. Vanguard Resource Group and Stout complete the list. Which one fits depends on your industry and deal size.

Objective states 500+ M&A transactions, with a footnote that some engagements were completed by a principal before joining. Sugar Tree states it has advised on over 100 transactions. Fleetridge Pacific says it has completed hundreds of transactions nationwide since 2003. Vanguard Resource Group says it has sold over 850 businesses. LR Tullius publishes counts only for individual bankers: over 200 for Lance Tullius and over 100 for David Shankar. All counts are self-reported and unaudited.

Sugar Tree Capital lists Food & Agribusiness and Specialty Services. Fleetridge Pacific advises on healthcare businesses such as home health, home care, hospice and physician practices. Schwartz Advisors focuses on the motor vehicle aftermarket. Objective lists six industries, and the other firms state no narrow sector.

Each firm's own page shows an address in San Diego, La Jolla or Encinitas. Two caveats apply. Objective labels its San Diego address a registered office for legal and administrative purposes that does not accept mail or visits. Stout lists investment banking as a service, but its locations page does not tie that service to the San Diego office. Ask each firm which banker would run your sale and where that person sits.

Only some firms say. Sugar Tree states enterprise values from $20m to $500m. Vanguard Resource Group says its typical transactions range from a few hundred thousand dollars to a few million. The other pages read for this guide state no size range, so ask each firm for its three closest comparable sales.

Vanguard Resource Group states a typical range of a few hundred thousand dollars to a few million, the lowest band stated by any firm here. A brokerage process and an investment bank mandate are run and priced differently, so ask each firm how its process works before you sign.

None of the pages read for this guide publish a fee schedule, so this guide states no fee figures. Ask each firm for its fee structure in writing, including any retainer, the success fee basis and any tail period.

ProCloser publishes this page and assigned the tiers itself, using three things stated on each firm's own pages: deal focus, a disclosed deal count and sector breadth. Tier A firms state 100 or more transactions and a defined M&A advisory practice. Tier B firms show a San Diego-area office and an M&A focus without a firm-wide count. Tier C covers a business-sale firm aimed at smaller sales and a multi-service firm whose San Diego page does not tie investment banking to the office.

The index holds 2,211 technology and software acquisitions as of October 31, 2026. It has no location field, and a search for San Diego-area place names and for the eight firm names in its deal and advisor fields returned no matches. The San Diego sample is under 10, so this guide states no valuation multiple and no buyer mix for San Diego.

Ask for three closed sales near your size and industry with the buyer on each, who will run your process day to day, which buyers they would call first and why, how fees work, and how long the engagement and tail period last.

ProCloser is not an M&A advisor, runs no sale processes and takes no success fee on any transaction. It operates a matching service that introduces sellers to advisory firms and may receive compensation when you connect through it. That is a conflict, so read the disclosure at the bottom and verify each advisor yourself.

Firms were left out when their own page could not be reached or showed no San Diego-area office. One site refused the connection, one was a parked domain, one showed an address in another state and one own site could not be found. Directory listings were not used as a source.
