Meet Our Team

JJ Mack

Team Lead

JJ Mack has been helping clients with mortgage financing since 2005. With a Bureau of Real Estate License, National Mortgage License (Federal and State), and training in ethics and mortgage lending best practices, he brings deep industry knowledge and experience to every transaction. The Mack family has built a trusted reputation in mortgage banking and brokering over two generations, making JJ much more than just a loan officer — but a trusted mortgage expert.

JJ’s business is built on relationships and education. He takes time to help clients understand the mortgage process, including debt structure, income, investments, and the financial decisions tied to homeownership. JJ attended Pacific Union College and lives in Penryn with his wife Megan and their three daughters. Outside the office, he’s usually training for his next race or focused on faith, family, and long-term growth — fueled by discipline, strategy, and strong coffee.

Lisa Fink

Sr. Loan Processor

Lisa Fink has become a wonderful asset to the JJ Mack Team. She works behind the scenes to make sure that all the paperwork and documentation gets submitted correctly. She also keeps every loan on track and validates that we close our clients homes on time or earlier. With an array of experience from working at a title company, to an assistant to a loan officer and as a processor, she has seen the mortgage process and how it happens in different ways. This allows Lisa to understand what needs to happen on every situation in order to help our clients get the loan they are looking for without a hitch.

Lisa’s best qualities are that she is highly motivated, she takes great pride in her work and is a team player. Some of her favorite things are camping, being outdoors and BBQing with her family.
