• Substantial Federal court litigation experience, including discovery, taking and defending fact and expert witness depositions, briefing, and oral advocacy.
• Extensive State court experience, including writ practice in Superior Courts and substantial appellate advocacy experience briefing and arguing cases before California Appellate Courts and the California Supreme Court as counsel to parties and amicus curiae.

In addition to practicing law and having a family, Melissa spends her free-time as a weekend equestrienne, real estate broker, and aspiring best-selling writer. Working on publishing her third novel and fourth book, she has previously published two legal thrillers under the pen name, M. T. Kingsley. All of the proceeds from the sales of her books go to charity, including the Anne B. Kingsley Ovarian Cancer Research Foundation that raises money to fund research for early detection of ovarian cancer, which prematurely took the life of her mother-in-law. Melissa loves to travel and hopes to one day become a spa critic when she ultimately retires from law practice.
