All of us at ZHA embrace the following core values and operate with these principles without exception.

Operate with the highest levels of honesty, integrity and fairness
Our most valued asset is our reputation, the high regard our clients have for our company, our employees, and the way we do business. We operate with the highest levels of honesty and integrity, and we are fair.
You can count on ZHA. That really means something in a world where expediency can overshadow integrity and where self-interest often circumvents honesty and what's right and fair. When we give clients counsel, we give them the truth. It may be unwelcome truth, but it is what they need to know to reach their goals.

Treat others as you would want them to treat you
The golden rule is platinum at ZHA. We treat our clients with respect, because we want to be treated with respect. We treat clients and all business associates professionally, because we want to be treated professionally. We value our team members because we want to be a valued member of the team.

Make all decisions for the best long-term interest of the client and the project
ZHA puts a client's interest first—before all other considerations. We look beyond project decisions that may bring immediate but perhaps fleeting benefits and determine whether it would be better to recommend decisions that may not bring immediate advantages, but will serve a client well over time.

Serve with passion and commitment
Bringing passion to a project energizes the efforts of everyone involved. Because we love our work, our enthusiasm spills over into the challenges we undertake. Not only are we passionate about our projects but we also are committed to them and to a client's success. Being committed is being responsive, and we are very responsive to our clients' needs.

Keep balance in your life
The ancient Greeks were onto something when they chiseled “Nothing in Excess” on the Temple of Apollo at Delphi. ZHA emphasizes balance in the lives of its employees. Although we are dedicated to our professions, we try to keep our work in the proper proportion to other aspects of our lives. We temper work with activities that keep us fresh, focused and excited about assignments.

Think outside the box
Be ingenious. Be intrepid. Be inspired. Sometimes an idea cannot take wing because it is trapped within the bounds of convention or weighted down by timidity or cliché. Like Michelangelo, who said he saw an angel within a block of marble and set it free, ZHA must be open to inspiration; and when we see an idea trapped within the commonplace, we must use our ingenuity to set it free.

Stay ahead of the issues
Anticipation and prevention go hand in hand. If an ounce of prevention is worth a pound of gold, so too is an ounce of anticipation. Anticipation means excellent planning and monitoring. If we can stay ahead of the issues, we can eliminate or lessen impacts to a project.
