Jeffrey Mack & Corey Mack

Two brothers. One business question: what is really holding the company back?

Elvis Cooper is a principal-led business transformation firm built by Jeffrey and Corey Mack for founder-led growth companies ready to remove one constraint and change how the work runs. Their work combines executive strategy, operating discipline, implementation, and responsible AI without treating technology as the automatic answer.

The company story

Strategy and implementation stay in the same room.

Jeffrey founded Elvis Cooper and leads executive strategy, growth, and commercial direction. Corey leads operating transformation, implementation, and practical AI leverage.

Clients work directly with both principals. The business question, operating design, executive decisions, and implementation do not disappear into separate sales and delivery teams.

Jeffrey is introduced first as Founder and CEO. Corey serves beside him as President and COO.

Leadership

Jeffrey first. Corey beside him.

How the brothers work

Business truth before business theater.

01Challenge the symptom
Do not prescribe against the first visible problem without tracing what creates it.
02Name the decision
Every engagement should help leadership make and carry out a real business choice.
03Stay close to execution
A recommendation matters only when owners, workflows, measures, and follow-through become real.
04Make AI earn its place
Use it when it improves understood work with proportionate safeguards and human authority.
