read moreMy parents used John for their estate and tax planning. They were so impressed I used him also. When my Mother passed away, we realized how much heartache and trouble John's work and advice had saved us. John is very smart. His work is meticulous and thorough. When my parents were still discussing things between themselves, John was very patient about when they signed the documents. We highly recommend his services.

Highly recommend!
I would like to testify as to the qualifications and expertise of my company's attorney, who has also become my personal counsel. His approach is direct, honest and committed to his client. With a dedicated work ethic, he tenaciously works in the interest of his client with a take-charge attitude that demonstrates his knowledge, honesty, enthusiasm and caring.

He is easily accessible to his clients, demonstrating authentic personal service and dedication to his profession, as well as the best interest of his client.

Not only is he a distinguished attorney but also holds a Degree as a Certified Public Accountant, which enables him to cross reference information to better serve his client.

I highly recommend John McDuff for legal services.

A Great Lawyer
John McDuff is a lawyer and a CPA. He is brilliant on how to best apply the law to win your case. He is thorough and produces excellent detailed documents. You can depend on John to get what you need done the right way. I was impressed with his ability to get into the mindsets of opposing counsel.

John attended a meeting with regulators with us in Austin. The regulator was viciously screaming out of control. John got up and blasted them at the top of his lungs, he is fearless and impossible to intimidate....At that moment I knew we had won a very comfortable position in the case.

He has an amazing work ethic that was always reassuring to us that he had our best interest at heart. We have had John represent us in several matters and the results were excellent considering the facts. He will leave no stone un-turned. We are and will remain long term clients of John Mc Duff.

Professional & Competent
I used John C. McDuff as my lawyer when I had a tax problem, and as a lawyer, I feel that I can say that he was perfectly professional and competent. I feel that the previous review was a mistake. John was very detailed oriented, and kept me well informed of the issues in my case, and he won it. I have referred others to him who were pleased with his work.
