For John, actions speak louder than words.

Coming from a business background himself, Antonczak understands the importance of continuous improvement—especially when it comes to problem solving. “Every business is different,” says Antonczak. “It’s important that your products keep pace with your clients.”


With 20 years of commercial banking under his belt, Antonczak doesn't spend much time talking about the awards he's won. To him success is ever-changing. “My clients rely on me to help them achieve their business goals,” says Antonczak. “Part of that is due diligence—making sure our credit team stays involved to ensure projections are accurate.”


Hailing from the Livonia and Novi areas, Antonczak has a great deal of experience working with the Finance and Automotive industries. “I'm excited to share my expertise here at Flagstar. It's refreshing to start somewhere new and help build a team of this caliber.”
