I am beyond grateful with the services of Attorney Osborne and the Shepherd & Osborne team. Attorney Osborne is extraordinary; you will not find a better lawyer than him. Not only is he a master tactician but his compassion and tenacity to fight for his clients is incomprehensible. I will never go to anyone else for any legal issues that may arise in the future. If you are in need of legal consultation or need some heavy artillery in a legal battle, try Shepherd & Osborne first. You wont be disappointed.

Mark is an exceptional attorney and an even better human being. My case had long odds, but Mark worked tirelessly and I came out relatively unscathed. I will forever be grateful not only for the service he provided but for his steady assurance in the most trying time of my life. I was also very impressed Krista. Very professional, correspondence in a timely manner and a wonderful disposition! If you need help these people will take care of you!

★★★★★ -Mikayla C.

We hired Mark Osborne for my husband’s driving case. This case could have made him a habitual offender which he could have lost his license for, and Mark was able to drop the entire charge. We knew right away that we wanted to hire him even after meeting with a few other lawyers. He was very personable, honest, and respectful. We would recommend him to everyone we know! We can’t thank him enough!
