Michael Wallenstein joined the firm in 2017 after nearly 10 years as a partner at two AmLaw 100 international law firms. Having spent his first nine years in practice as an associate and later a partner at the highly regarded real estate and public entity boutique firm Brown Winfield & Canzoneri, Michael has been pleased to return to his small firm roots where he can provide clients with the same world-class service and expertise at much more affordable rates.

Michael’s practice encompasses real property valuation, eminent domain, easement disputes, professional liability, employer liability, business torts, class action defense, Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) matters, wrongful foreclosure, municipal tax, civil rights, land use and contract and construction defect disputes. He has litigated claims for both plaintiffs and defendants spanning a wide range of matters involving hundreds of millions of dollars.

Michael has a particular expertise in railroad real estate matters and is well known in the industry. For nearly 25 years in this capacity, he has adeptly handled railroad title, eminent domain and other valuation matters as well as other real estate issues. He is frequently invited to speak on these matters. He also represents developers, transportation authorities, health-care providers, financial institutions, public entities, and a broad spectrum of companies and individuals in their real estate and general business litigation and counseling matters.
Michael has substantial first chair trial experience in numerous matters. He was co-lead counsel for the prevailing plaintiff in Union Pacific Railroad Co. v. Santa Fe Pacific Pipelines — a trial lasting 265 days over four years and selected by the Daily Journal as one of the "Top Plaintiffs' Verdicts by Dollar Amount of 2012."  He also successfully defended a local city at trial on a multimillion-dollar CERCLA claim. He has argued cases before the California Supreme Court and the California Court of Appeal.

From the outset of a case to trial, Michael continuously seeks creative solutions to drive settlement and reduce litigation costs. He focuses on connecting personally with both clients and opposing counsel, and uncovering overlooked facts and legal issues, often opening the door to solutions that others might miss.
