It was a very pleasant experience. Clark explained everything in layman’s terms. He pointed out the need for certain items—HIPPA for example. Notarized signatures were done “on the spot”, and his cost was very, very reasonable. I’d recommend Clark and his firm to anyone seeking estate planning. Bob F.

I sought Mr. Allison's advice on making significant changes to my trust, and then after another year, and based on developing circumstances, a further revision to the document. His advice was straightforward, easy to understand, yet absolutely comprehensive. I have every confidence that my will and trust documents are exactly as I wish them to be, and in full compliance with all legal standards, practices, and laws. Additionally, Mr. Allison is an approachable and available attorney, who responded to my questions, and put me completely at ease. I have recommended Clark Allison LLP to both friends and family, and will continue to do so.

Clark easily guided us through our new trust. Professional, friendly and informative. Everything was explained to us well. We will continue to work with Clark as needed to keep our trust current. I was dreading (and procrastinating) setting up our trust. I left his office feeling both relief that is was completed, and happy that it went so smoothly. I recommend Clark (and staff).

I needed assistance with establishing a trust for my Mother's Estate. The process was timely and accurate and I appreciated the work done on her behalf.

Recommending Clark to all of our friends. Clark spent copious time explaining our options and thoroughly answering all of our questions. Our family is now setup for long term success due in part to Clark.

We were referred to Clark Allison by our a Pastor and friend and so happy that we were. We had 2 complicated trusts and Mr Allison was able to explain our best options to avoid tax penalties. We also had to make a few changes a couple of years later. He was also available to answer any questions that came up along the way. We are very satisfied that living trusts are secure and won’t be any issues in the future for our children.
