Karol Dondero, Controller

(925) 934-8712


  • Contracts
  • Client billing
  • Insurance oversight

Qualities that clients and colleagues value:

I am hands on with all aspects of accounting for ADE. I follow through with accounting details so the clients get the invoices in the format they need them. I pay great attention to detail in all aspects of accounting. I keep everyone laughing even though I'm a “bean counter.”

What drives Karol:

I want to do everything possible to see the company succeed. I am willing to pitch in on any project where I can be of help, like when we did a study on the feasibility of installing yurts at a county park. I am the resident camping expert in the company, other than Doug.

Success story:

I managed the reconnection of our two locations via a VPN that had been “broken” for several years and have upgraded many systems within budget.
