About Us

different colorful doors 

The story of Guardian Mortgage begins in 1965 when a young man of common sense and uncommon smarts had a better idea. While building homes in Grand Blanc, Michigan, Jack Sweet saw firsthand how confusing and difficult it was for his home buyers to go through the loan process. He knew there had to be an easier way.

Jack wanted to treat customers the way he would want to be treated—by offering advice on which loan options best fit their needs and walking them through the process, each step of the way.

So Guardian Mortgage began and flourished. Customers appreciated the respectful treatment, honesty, and sound advice Guardian offered. And, they spread the word far and wide about a different kind of home mortgage company.

Today we originate loans in 40 states and have helped over a million homeowners realize their dreams of homeownership.  These are not just numbers. Our greatest source of pride comes from our clients’ satisfaction.
