Former HCA CFO Sam Brooks joins Vanderbilt nephrologist and Texas businessman Dr. Harry Jacobson to form Renal Care Group.

It will become the fourth-largest publicly traded dialysis chain in U.S. and generate multiple other dialysis chains that call Nashville home, such as Renal Advantage, NNA, National Renal Alliance and others.

Dr. Jacobson will go on to serve as vice chancellor for health affairs at Vanderbilt University.
