Greymar Partners was founded to provide professional valuation and transaction advisory services to privately-held companies.  

Greymar Partners was founded by Enrique Mayer, ASA after a 20-year career working as an equity valuation analyst with a private equity firm, senior financial analyst with Qualcomm Personal Electronics (a joint venture between Qualcomm and Sony), Manager of Valuation Services with a nationally-recognized valuation firm, and Managing Director of Investment Banking and Valuation Services with a Wall Street investment banking firm. 

Unlike other valuation services providers, whose professionals depend on their backgrounds in accounting or litigation, Greymar Partners was born from the experience and expertise gained from analyzing, advising on, and negotiating corporate finance transactions, from the buy-side and the sell-side, at private equity and investment banking firms.  We know how to measure the value of a business or business interest in a transaction setting because this is what we have specialized in for decades.

Greymar Partners has earned an impeccable reputation for technical competence and old-fashioned customer service.  Our guiding principle and commitment are to remain true to the highest level of ethics and standards—while always putting our clients’ interests first.
