John Phillips

Methodist Health System has a new leader at its flagship Dallas hospital.

John Phillips, who has been the head of Methodist Mansfield Medical Center for the last seven years, officially took his perch at Methodist Dallas Medical Center on Monday.

Phillips takes over for Dr. Martin Koonsman, who has moved up the chain to become the system’s chief medical officer.

In Mansfield, Phillips grew the hospital to 254 beds and helped it gain a Level 3 trauma designation as well as a Magnet designation, given to top performing hospitals for nursing.

Phillips held CEO and COO positions within Irving-based Christus Health and Abilene-based Hendrick Health System before joining Methodist. He started out as a physical therapist before earning a Masters of Business Administration and Masters in Healthcare Administration from Trinity University.
