About the firm
A family firm, built out of operating companies.
Corporate Advisory Group works across land development, water and wastewater, district formation and finance, industrial facilities, international manufacturing and sourcing, and technology. Four principals, working out of Conroe, Texas.
Why the firm exists

Corporate Advisory Group is a family firm with four principals. It exists because the people in it have run the businesses they now advise on: land developed and subdivided, private utilities built, permitted and operated, treatment plants designed and commissioned, a manufacturing facility built from nothing in another country, equipment sourced and inspected abroad.
Most advice about a project comes from someone who has read about the work. Ours comes from having been answerable for it, including for the parts that went wrong. That is what the practice is built on, and it is why the disciplines sit together in one firm rather than in separate ones. A project of any size rarely respects the boundary between them.
Operating rules
Four rules that decide most projects.
Start with the constraint, not the scope
One thing usually decides a project: a permit, a utility, a supply, a delivery date, or a regulator’s calendar. We find it before writing a proposal.
Work back from the outcome
What a project has to end with, a discharge route, a shipping deadline, an occupancy date, sets what everything upstream has to be. Deciding it last is how projects get rebuilt.
Name who is doing what
Licensed design, legal and municipal advisory work is done by licensed and registered professionals. We say which firms, and we manage them.
Date everything
Rules, prices and lead times all move, and Texas water and land rules are moving quickly right now. Anything we publish or hand you carries a date and its sources.
How the work runs, step by step
The four rules above decide what a project needs. These ten are the order the work itself goes in, whichever discipline it sits in.
- 1. Understand the objective.
- 2. Build the right team.
- 3. Know the numbers.
- 4. Understand the technical issues.
- 5. Use technology intelligently.
- 6. Coordinate the professionals.
- 7. Challenge assumptions.
- 8. Anticipate problems.
- 9. Make decisions.
- 10. Execute.
What we do not do, stated plainly
We scope, procure, coordinate and manage. We do not sign off work that belongs to a licensed professional, in any discipline, and we name the firm that does.
That line matters most where a mistake is expensive: sealed engineering drawings, advice to a municipal entity on issuing securities, legal opinions, and the certifications behind equipment and construction. Where a project needs one of those, we say so early and work alongside whoever holds it. The small print at the foot of every page states the two cases that come up most often.
