I have used MAO for the past 8 years and have been extremely satisfied with all aspects of their land work.  They are capable of handling all of my needs in the field with lease acquisition, title, abstracting, surface damages and mapping.  The quality of the brokers that they provide has been far superior to other shops in our current environment.  Their utilization of new mapping GIS system and their up to date data base has saved us time and money on our projects.”

Whether the services have been basic lease checks, leasing, title and abstracting, due diligence, damage settlements or miscellaneous other Land/business related activities, the work product has always been completed timely and of high quality. MAO employs an experienced staff that is capable of handling routine Land work as well as more complex Land issues. MAO and its staff are honest and operate under the highest ethical standards.
