Financial institutions—national banks and mortgage lenders—turn to John when facing litigation over the origination and servicing of consumer loans. These cases often involve claims of lender liability, breach of contract, unfair business practices, fraud, negligence and alleged violations of the Truth-In-Lending Act (TILA), Real Estate Settlement Procedures Act (RESPA) and similar consumer protection statutes.
John also defends clients in consumer class actions, with experience spanning California’s Gift Card Law, the Song-Beverly Credit Card Act, the Consumer Legal Remedies Act (CLRA) and California’s Rosenthal Act. He is well-versed in all phases of class action litigation, including coordinated proceedings in California state courts.
