also known as Nii
I entered the legal profession because I have a strong passion to serve others. This passion and "do whatever it takes" attitude has afforded me experience in number of legal practice areas, including: criminal defenese, commercial litigation, divorce and custody diputes, and bankruptcy. Prior to opening up my law firm I had the privilege to serve as the President of the University of Idaho College of Law Student Bar Association, and as Lieutenant Governor of Membership and Communication for the American Bar Association Law School Division’s 12th Circuit. These positions sharpened my skills for advocacy, negotiations, and clearly communicating the needs of those who entrust him with their issues.

"I endorse this lawyer as he was always prepared. He always advocated for his client until the very end. The thing that really makes a family law case move along at a pace that is good for the client is a lawyer like Mr. Ollennu who always timely returns calls and responds specifically to questions and proposals from opposing parties."
"I fully endorse endorse Nii as an attorney. We tried a case together this year - and his help and insight proved invaluable to the case. Since then, I have had the privilege to get to know him even better. He exhibits deep compassion for his clients and their situation that can be very rare in the practice of law - especially in criminal defense. I can recall not too long ago - I read a Facebook post by him after a long, hard day of work at the courthouse where he expressed how "he only wished he could do more." To me - that summarizes his passion for practicing law, and the genuine concern and care he has for those he represents. He is a fine attorney, he is bright, intelligent, and as a fantastic future ahead as a lawyer. I am proud to call him a colleague, and a friend."
