“Nobody understands the client’s issues better than the client, and so it’s important to listen to the client and learn how best to help solve the client’s issues in a thoughtful, yet efficient and cost-effective manner.”

Once fully understanding the client’s issue, Mark Trenner explains all options to his clients in plain English.
