What Clients Are Saying

“Chaille Walraven at Graft & Walraven was a tremendous help to our family. She was extremely knowledgeable in the area of oil & gas law.  As a land owner and royalty owner we knew that we could not challenge the large oil companies alone.  Not only was she able to quickly review our rights under our mineral lease but was able to challenge the oil company who was violating the terms of that lease. She was able to settle the dispute quickly and was able to avoid a long drawn out trial.  Her services were invaluable and we won’t hesitate to use the Graft & Walraven law firm again."

"Sara Bondurant has been amazing to work with through the process of approval for Medicaid for our mother. She is very knowledge in the area of the legal rights of the elderly. With my being out of state as well as both of my brothers, she has been so helpful and accommodating with three different time zones, answering our questions, walking us through the applications and appeal process and so much more. I highly recommend Sara for any need advice or guidance with Medicaid and/or legal assistance concerning Medicaid and Eldercare. Thanks Sara!"

"I inherited some acreage of mineral rights from my mother that had an existing shallow well lease that paid a tiny annual royalty. Frankly, it cost more to file the non-resident OK tax return each year than I made on royalties. But I knew something was up when I started getting unsolicited letters from landmen wanting to lease/buy my rights. I had no idea what the "real" value was so I what anyone would do...I Googled "Oil/Gas attorneys in Custer County, OK". Fortunately, G&W was on the top of the list and I gave them a call. They immediately made me feel comfortable and answered all the questions I had, no matter how silly or stupid. Long story short, not only did they get me a great price for my rights but they handled the negotiations to cancel the existing lease, thereby freeing me up to move forward with the sale. At every step along the way, they kept me informed, responding quickly to any questions or concerns I had. I have no doubt I wouldn't have done nearly as well had I tried to manage this process on my own. G&W's knowledge and expertise made all the difference and I recommend them without reservation."

"Mark Walraven was the only attorney that called me back out of 5 that I had contacted to assist me and my siblings/cousins regarding a matter leading to possible inheritance of mineral rights. If didn't work out the way we hoped, however Mr. Walraven was prompt in reviewing the documentation, providing information, answering the many questions I had and explaining why we didn't have any recourse. He even responded once on a Sunday (which would is unheard of where I live). I would definitely recommend his/the firm's services to anyone needing such help. He was extremely friendly, unassuming and put me at ease very quickly on a subject I knew nothing about. Oh.... I stand corrected... One other attorney did call me back.... a little more than 2 weeks after I had completed conversations with Mr. Walraven and only to tell me she had finished confirming there were no conflicts of interest and she could now answer questions for me. Too little, too late."
