JJ MACK
BRANCH MANAGER
JJ Mack has been helping people with their mortgage financing since 2005. He has received several different forms of credentials that allow him to be much more than just a loan officer, but a mortgage expert, starting with his Bureau of Real Estate License, National Mortgage License: Federal and State and also the Ethics and Mortgage Lending Best Practices Schooling. The Mack family has been in the mortgage banking and brokering industry for two generations, building up the Mack name for people to know and trust.
JJ’s business is built on one solid foundation – relationships. He takes pride in educating his clients. JJ tries to make it a point to meet with every client and help them understand the process of a mortgage loan. This includes discussing a client’s debt structure, income, investments, among other matters that relate to a success in Real Estate. JJ feels that the more he can educate his clients on, the better they will be when it comes to making their most important financial decision; home ownership! Because of this his clients become raving fans! JJ Mack went to Pacific Union College, is married to Megan and has two German Shepherd dogs. When JJ isn’t helping people succeed in home ownership he enjoys traveling, hiking and skiing at his favorite getaway place, Tahoe.

LISA FINK
SENIOR 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.
