Client feedback
What Collin County clients say
Feedback from clients in Plano, Frisco, Allen, and communities throughout Collin County.
I had suspicions and needed facts, not guessing. Their investigator worked around the Frisco and McKinney traffic and got clear photo and video documentation. Fair pricing with no surprise charges for mileage or weekend work. Highly recommend.
From the first call in Allen they were straightforward and respectful. The surveillance was handled quietly, and the timeline and report were organized well enough for my lawyer to use. Grateful for how they handled a stressful time.
