  • Mervyn Craig Thompson

    I endorse this lawyer. I have known Ron for many years. When a client of mine gets in trouble with the law I refer them to Ron and Jason. If I ever got arrested Ron and Jason would be my first call.

  • Heather Dawn Shand Perkins

    Ron is an aggressive and compassionate criminal lawyer that prides himself on obtaining good results for his clients. He has an eye for seeing procedural and technical errors that have helped his clients cases tremendously. He is not afraid to put in the time and effort needed to ensure his clients cases are handled individually to address each cases nuisances. I highly recommend him for all types of criminal cases.
