David A. Grabhorn, ESQ., Senior Attorney


About Mr. Grabhorn

David A. Grabhorn is a Senior Attorney at the Temecula Valley office of Messina & Hankin LLP.

He came to the Firm after an extensive career in the labor movement, during which he successfully chaired literally hundreds of collective bargaining negotiations throughout the United States. He has dealt with nearly every major newspaper chain and commercial printer in the United States, as well as with the largest paper and packaging corporations in the world. The types of negotiations through which Mr. Grabhorn has guided clients run the full gamut of first time contracts, to routine contract renewals, to plant acquisitions, to plant closures—and from small single plant bargaining units to multi-plant operations owned by multi-national corporations.

Just as some of the most effective defense lawyers for those accused of white-collar crime are former federal prosecutors, and some of the most effective tax lawyers are former IRS agents, Mr. Grabhorn has been able to effectively represent companies by obtaining their objectives efficiently. There are any number of mammoth law firms claiming to have achieved success after extracting a king’s ransom from the client in legal fees. Real success must be efficient, because it is of dubious value for a company to give up more in legal fees than all the economies it obtained from the transaction itself.

Mr. Grabhorn’s experience includes practice before the National Labor Relations Board, labor arbitration, and federal WARN Act, EEOC, ERISA, and FMLA litigation. He has successfully represented employers in their dealings with executives, exempt and non-union personnel. He has obtained agreements acceptable to the client companies for the beginning and ending of employment, or defended against wrongful termination cases in state court.
The volunteer and pro bono work donated by Mr. Grabhorn began in college when he read for the blind; it continued after law school when he assisted animal rescues and set up a charitable trust that delivers 100% of donations by unpaid trustees.
