About the Founder
Mary Dinkins
The Dinkins Team was founded by Mary Dinkins, a mortgage industry leader whose career began in 1981. Over more than four decades, Mary built a legacy of excellence, helping thousands of families achieve homeownership while earning recognition as one of the nation's Top 100 Loan Originators. With more than $1 billion in lifetime loan production, a client return rate exceeding 90%, and a reputation as a nationally sought-after speaker, her dedication to service, expertise, and lasting relationships became the foundation of The Dinkins Team.
