Exceptional Attorney
I live in Maryland and hired Mark to represent me with a wrongful mechanics lien placed on property I own in Ohio. I could not be more pleased with the way he handled my case!

Excellent Representation
I retained Mr. Ondrejech to co-counsel a case with me in the Cleveland area and I must say he is nothing short of outstanding. Mr. Ondrejech is an excellent, experienced and compassionate attorney. He is dedicated to his clients and aggressive when necessary. I high recommend him.

Mark Successfully Helped Me Get through the Worse Legal Nightmare in My Life
This is one of those reviews you can take to heart - it is totally unsolicited and probably unexpected, and from the head and heart. I don't know Mark outside of his representation of me, and yet I couldn't be more enthusiastic about endorsing him than I am here. He's an excellent, determined, honest, and dependable attorney who has represented me in multiple cases and has always done an excellent job. Notably, when the local court refused to simply follow the law, Mark helped me take my case to the next level - the Court of Appeals - where I prevailed thanks to his excellent and diligent representation. He has expertise in both civil and criminal law, and I strongly endorse him and am writing this review as a thanks for his outstanding representation - and nothing more. I wrote this same review on Facebook because I believe in it strongly. Erik
