Biography

Mack Grubb, PA-C, is a Texas native who practices adult internal medicine. He completed his physician assistant training at the University of Texas Southwestern and is board-certified by the National Commission on Certification of Physician Assistants (NCCPA).

Mr. Grubb pursued adult internal medicine because he’s fascinated by the body, loves science and has a strong desire to help people. He loves that adult internal medicine allows him to develop long-term relationships with patients and help them navigate and manage the complex healthcare environment. Internal medicine is also central to preventive medicine, which is his passion.

Mr Grubb’s favorite part about being a clinician is helping patients have a better quality of life. He believes healthcare is a partnership. He’s in the passenger’s seat and his patients are the drivers. He provides navigation and direction, but ultimately, patients hold the wheel, make the final decisions and determine where they go.

Mr. Grubb is married to his wife, who is also a PA, and together, they have five children—three girls and two boys. He enjoys spending time with family and friends, playing soccer and staying involved with his church.
