The McKinney Attorney Who Treats You Like Family

Personalized Service for Every Client,  Every Time

You and your attorney should have a genuine connection. Across our various areas of practice, clients repeatedly say the same thing: We care and are there for them. To us, this comes naturally because we aim to establish a true relationship with every client who walks through our doors. These relationships are what motivate us to work as diligently for our clients as we would for our friends, neighbors and family members.

Case Results

Client was arrested for Violation of a Protective Order after being arrested by officers for an unrelated driving offenses. At this time of this arrest he was borrowing a friend’s car to run a few errands. Approximately a year prior to this arrest, a default protective order had been granted against this client. A provision in that protective order made it a crime to possess a firearm. During an inventory search of the vehicle, a semi-automatic rifle was uncovered in the trunk of the vehicle. The client made the decision to have a jury trial. After deliberations, the jury returned a verdict of not guilty.

Jury Trial—Not Guilty

Client was arrested for Driving While Intoxicated after being pulled over by police for speed. A blood test taken after this stop alleged my client’s blood alcohol level (BAC) at the time of the test was .216, resulting in this case being charged as a Class A Misdemeanor. After extensive discovery review, and persistent negotiations, the prosecutor agreed to lower the charges to a first DWI. This reduction was important because it reduced the punishment range, and the client was able to save $3,000 of dollars in DPS surcharges.

Reduced from Class A Misd. To Class B

Client was driving home from a birthday party when pulled over for failure to signal a lane change. The client was subsequently arrested for Driving While Intoxicated. The breath test taken at the police station alleged that my client’s BAC was .112. After pointing out some significant weaknesses in the case based on evidence in the video and officer’s report, the prosecution agreed to offer a reduction to obstruction of a passageway, and allowed my client the opportunity to have the case dismissed after successfully completed deferred adjudication probation.

Reduction to Obstruction w/ Deferred Adjudication

Client pulled over on a major highway for speeding and a missing tail light, and was subsequently arrested for DWI 2nd after the officer saw two open containers of beer in the cup holders. At the Administrative License Revocation (ALR) hearing we successfully argued that DPS could not establish my client’s alcohol concentration at the time he was operating his vehicle. The Judge found our argument persuasive and denied the request by DPS to suspend my clients driver’s license.

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.


I hired Nii-Amaa for legal counsel back in the middle of 2016. Upon hearing what he had to work with, he gave no promises. But the confidence that he exuded when he claimed he could help didn’t go unnoticed, and for good reason. He was affordable, and extremely efficient at his job. When meeting him there for my first appearance, not only was he able to get the case heard early, but he walked out of the DA’s office with charges dismissed! I would give him ten stars if I could!
