About me

Mr. Markham is a San Diego attorney who obtained his law degree from Harvard Law School in 1987. He is an experienced, successful litigator of complex business and real estate disputes, and he has litigated a wide array of such matters for plaintiffs and defendants in California since 1988. He has won jury verdicts and bench trials, and he has handled major antitrust litigation and complex commercial litigation in closely contested matters (click here for more details). More generally, he has obtained superb results time after time for his clients, who have included major companies, established firms, entrepreneurs, investors, and others.
