2
Practice areas

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.

Fulfilled his promise
Nii has fulfilled his promises on 2 cases for me. One of them being divorce and the 2nd was a false claim that he had dismissed for me. Nii is a truly amazing person and attorney! You're in great hands when Nii is on the case! Thanks Nii!

Nii Amaa is amazing
I was charged with a DWI and some how managed to get Nii Amaa as my court appointed lawyer. He was absolutely perfect. I never felt like I was an after thought or burden as I expected to with a court appointed lawyer. My case was complicated and he took the time to look into every single little detail and kept me in the loop every step of the way. He was very straight with me throughout the whole process, so I never felt like I was given false hope or the impression that he was slacking on my case what-so-ever. For my charge, we decided that we would take my case to court instead of settling for a plea deal. However, before it even got there he got my case dismissed! Of course every case is different, but I do not think I would have had the same out come with any other court appointed lawyer, and probably not even a hired lawyer. I felt like Nii Amaa really listened to me and cared about my case. He’s a whole-hearted and genuine person and I will always go to him if I ever need a lawyer.

Best of the best
I could not have asked for a better lawyer. With this being my first time ever hiring a lawyer and having to deal with the court system, Nii was so completely understanding and always available. He shows you a strong willingness to work for you and gives you a sense of confidence and safety that I've heard can get lost with other lawyers. He made sure to keep me informed and updated and was able to get everything completely disposed. I am forever grateful to have been lucky enough to retain such a knowledgeable and personable lawyer and I will refer anyone and everyone who may ever need legal help to him.

Criminal Law - Client
Nii Amaa provided great service from the start. He showed interest and remained very patient as I explained my situation. He was also very flexible and made himself easily available. I could either call him or message him depending on the importance of the situation. Overall, very professional, respectable and very helpful.

Fantastic Service
We hired Mr. Ollennu to assist us with obtaining emergency custody of a child. He not only built a great case but worked with us on payment options since we were not prepared for this expense. He won our case and made it a painless process for us. I would highly recommend them to anyone seeking a lawyer.

Wise, kind, and honest- a rare combination
I couldn't recommend this attorney any higher. Wish there were a way to give more than 5 stars! I had a need for a Texas attorney though I reside in a different state. He was readily accessible and available, exceptionally polite, didn't overcharge, and gave us his honest opinion when we were starting to go off course. Thank you Nii Amaa for your wisdom that you display with kindness and honesty.

Probation issue
I had been having issues with my car that had my interlock device in it. I kept having battery issues and my car completely died and took almost an hour to get any charge to it which is a big issue with interlock calibration. Once I got my car able to start I went straight to the store bought a battery and took it to my interlock service location and had them install it in the car so that I wouldn't have tampered with it. With just trying to start my.car from it being dead I got multiple violations for charging and getting my battery replaced. When I went in for my probation meeting they told me because of all my power violations from the battery I would have to serve two weeks in jail. I called my attorney Mr. Ollennu who contacted my probation officer and got it dismissed as long as I got my car repaired and serviced. I thank him so much as later that month when I was supposed to be serving my two weeks my dog of 9 years became very I'll with a brain tumor. Without his help I would have been having to serve time for mechanical issues while my dogs health rapidly declined leading to his passing. I am forever greatful for his dedication and understaning to help those in need of his professional knowledge of the law.

Personable and Professional
I am embroiled in a multi state dispute and after months of no positive outcome I approached Nii Amaa Ollennu for assistance. Nii Amaa is not only knowledgable but personable as he patiently answered many questions over a period of months. Finally, there is hope for a resolution to this stressful issue and it is due to Nii Amaa's perseverence.

Nii Amaa Ollennu comes to the rescue
After being given conflicting information regarding a challenging legal situation I consulted with Nii Amaa Ollennu. He immediately took action, providing updates at every juncture. I may have a PhD but when it comes to legal issues I felt like a damsel in distress. Nii Amaa has definitely saved the day.

Best Rates in the DFW
My experience was amazing! I was applying for a OCL and Nii Amaa was able to help me get all the paperwork needed in order to file and made the process smooth and easy. When I was researching on how to get a OCL the process seemed very complicated and I was told over the phone that I could do it myself. This seemed impossible. I called around to attorney's to get prices and Nii Amaa's price was the best! He also promised to not only give me the best deal, but that he would make sure he had the job completed for the rate he quoted, even if he had to go back to the court for any other reason! He was easy to get a hold of and answered my questions in a timely manner. He was friendly and helpful! He was the perfect help to a very complicated situation of mine!

Top-notch criminal defense lawyer!
I found Nii's law firm by doing a simple search on NOVO. From my first phone call with him, I could sense genuine concern in his voice and that he really cared about his clients. He quoted his price up front and went immediately to work the next day preparing paperwork for my husband's release from jail. He made himself available by answering and returning phone calls and emails in a timely manner, and was very patient when answering all my questions. When he called to tell me that my husband was being released after 9 days in jail, I couldn't help but shed a few tears over the phone. All the while he was very understanding and allowed me time to compose myself as well as offered words of encouragement before we hung up. On my trip out of state to pick up my husband after his release, Nii was gracious enough to provide me with directions to the jail via text message and even took the time to meet us at the facility for hugs and a quick selfie before we hit the road back home! This sort of attentiveness from a lawyer is practically unheard of in today's world, which makes Nii's brand of service all the more special. Nii is the most humble and gracious lawyer I have ever met. He sincerely cares about his clients and it showed in the way he took care of business for my husband. He comes from a long line of public servants, so helping people is in his blood. For anyone looking for a top-notch criminal defense lawyer, I would highly recommend Nii Amaa Ollennu in McKinney, Texas. His legal skills and customer service are exceptional!

If I could give him a 0 star I would
Custody case was very complex and needed a lot of knowledge and leg work. He did not do his job and I ended up forking out thousands of more dollars trying to fix his mistakes. He blew through my money, and did not do his job. I did basically everything and he even stated in court that he needed a continuance because he was not prepared. I will never forgive him for the emotional and mental destruction he has caused in our custody case.

Correction to my Earlier post
The paralegal left me in tears. She did not have all of my paperwork. I requested a meeting via phone to clarify what she had and to fill in the gaps. I gave Nii all of the details of my particular case. She accused me of writing a false review on their law office’s performance, but I did not have all of the facts as to why she decided not to take my case when I wrote the previous review. I have more of them now, but unless she provides them to me in writing, I will not know what they are. I am devasted. I don’t feel good and now I have to find another attorney. When the Stowers demand letter was promised in February, she was unwilling to have a person to person accounting of the paperwork and told me, via email to go somewhere else. This law firm is unkind, unfair and unethical. Her email opens like this, “I’m sorry if you feel slighted by our decision, but if you are going to post bad reviews about our firm, you should at least get your facts straight beforehand. The medical records are the problem.” None of the examples she provided were ever clarified from her. She was missing paperwork. She also mentioned employment records were problematic. Without evidence, (all of my medical records), which I thought she had-but only piecemeal, she continued, “There is compelling evidence indicating that your back issues existed prior to the accident, and you were attempting to use the accident to recover funds that you were not owed. As for your grievances and bad reviews, you are entitled to your opinion, but you must report the facts (not your version of the facts). We will return your records at our earliest convenience, and we consider this matter closed. Please feel free to have any agency contact our firm to discuss your grievances. I am more than happy to provide them whatever they need to resolve this matter as quickly as possible.” She was absolutely difficult and unwilling to work with me.

To me - that summarizes his passion for practicing law, and the genuine concern and care he has for those he represents.
