Our Values
When Mason-McDuffie Mortgage was established in 1887, its founders were guided by core principles centered on serving customers with committed employees. During our more than 120-year history, these core principles have formed the heart of who we are today.

  • Service - Providing superior customer service keeps them coming back.
  • Flexible and Adaptable - Embracing change to meet the needs of an ever-changing market.
  • Teamwork - Striving toward a common goal leads to success for all.
  • Integrity - Requiring  honesty and ethical behavior in every transaction.

Our Culture
Our employees are our Number One asset. To recruit and sustain a team of the best and the brightest in the lending field, we provide an environment that fosters professional growth and career satisfaction. The  happy and well-balanced work atmosphere we maintain allows our experienced staff to consistently provide exemplary customer service. A loyal and growing clientele served by a dedicated and reliable team, grows from this solid foundation. We are privately-held by the senior management team so decisions are driven by what is best for the company and its clients, not to meet demands of outside investors.
