Jonathan is the president and founder of Guaranteed Financial. He started his career in the mortgage industry at the age of seventeen. After holding several positions among three different companies, he eventually became a Senior Sales Manager at a large mortgage company. At the age of twenty one, motivated by what he saw as inequities in the industry, he set out on the journey of creating a new type of Mortgage Company. One that wasn’t solely focused on its bottom line and the “profit maximization” approach of the time, but rather a company that would embed itself into the communities it served. A company that would leave a social impact.

Now in its twentieth year of existence, Guaranteed Financial has maintained itself as a dependable and seamless source of residential financing for hundreds of families and borrowers and is now a staple in its headquartered town of Berwyn, Illinois. Together with his team of experienced and entrepreneurial-spirited mortgage professionals, Guaranteed Financial is on pace to grow substantially in the years to come.

Jonathan holds both a bachelor’s degree in Business Management as well as an MBA in Finance from DePaul University in Chicago. Jonathan recently served on the board of the MBA Association at DePaul University. Jonathan was also a member of a Honduras Microfinance Brigade team whose mission was to bring basic financial structures to villages across the impoverished country. On his free time, Jonathan enjoys woodworking and traveling the world with his family. In the summer of 2024, Jonathan, along with his wife and two boys, visited their sixty-third country.
