Team


Our Executive Team

REZYFi, Inc. and its operating subsidiaries, ResMac Mortgage and REZYFI Lending, were founded by industry-leading mortgage, real estate and banking professionals.

Through their connections, subject matter expertise, and more than 50 years of combined industry experience, the team has grown the organization. The level of success achieved by this team can be attributed to early capital infusion by the executive members, a strong southern California mortgage and housing sector, management foresight to expand into other states, and likely most importantly to direct involvement in the day-to-day operations of the business by the executives, who are also the majority shareholders and primary funders of the corporation.
