Mr. Mase started with The Ryan Firm in 2015 as a young litigation associate and quickly established himself as a key member of the team. Nearly immediately, Mr. Mase was trying cases as second chair for critical trials and was deeply involved in the appellate and law and motion practice at the firm. Within his first year, he tried and won Los Angeles’ oldest unlawful detainer case. After successfully honing his trial, law and motion, and appellate advocacy skills, Mr. Mase was promoted to firm Litigation Manager in 2021 and was key to The Ryan Firm’s stellar 2022 appellate performance. In 2022 alone, Mr. Mase obtained four reversals and one opinion affirming various judgments and orders. Since that time, Mr. Mase has further refined his strategic thinking and leadership skills. He now works with each of The Ryan Firm’s litigators to ensure that each case plan is executed strategically, ensuring that client goals are met. Mr. Mase also works with each member of The Ryan Firm Litigation Team to produce work-product that is the best in the industry.
