I am pleased to recommend Ilana Sharpe for all your estate planning needs. I had known for years that we needed to prepare for the future, but it’s not a fun topic and I kept putting it off. If only I had known how easy it would be to work with Ilana, I’d have checked this off my list a long time ago. From our first meeting, she put us at ease and helped us understand our options. She made our responsibilities clear and stayed in communication to make sure the work was completed in a timely manner. Within a matter of weeks, we had an estate package in place, and I sleep easier knowing that we will not put undue burden on our family if the unthinkable occurs.

From business contracts and licensing agreements to personal estate planning to litigation, Mark Robertson has been a trusted attorney and advisor for many years.  Mark has the rare quality of being able to get to the heart of a complex matter quickly.  His experience, calm demeanor, good judgment and wisdom have been invaluable.  I hold Mark in the highest regard, both professionally and personally, and he has my enthusiastic recommendation.


I have known the Robertson Williams Law Group for over thirty years. I know they are one of the most professional and knowledgeable law firms in Oklahoma.  They provide me advice in my corporate, real estate and my firm’s consulting clients issues with total overall competence in addressing business issues.

I also engage with them my personal estate planning providing me with my Last Will and Testament planning and keep me updated annually on changing new laws and estate tax issues.

I highly recommend to my friends and clients the Robertson and Williams Law Group.

Mark has worked with my wife and I on estate planning and recently Mark’s law firm helped on my mother’s probate. The thing I appreciate most is the quality and promptness of his work.
