Critical Friends Testimonials

What our people say about us...

At a time of real personal crisis both Ashleigh Harold and Andy Nightingale of CFL provided me with outstanding service and support, when I reached out to them for help. Their caring attitude, empathy toward the situation I was in and their ability to put me at ease through a very difficult period was truly exceptional.

Company Director

Sector business

I have known Andy for over 30 years and can confirm his outstanding police service and commercial career. Andy is one of the most outstanding investigators, managers and human beings I have ever worked with. I have absolutely no doubt about his honesty, integrity and professionalism.

Former Senior Police officer and Superior

Sector business

Ashleigh is an eminently regarded lawyer who I have co-defended on many cases over the years. She brings a vast wealth of experience to her casework and a meticulous attention to detail. Easy to work with, her empathy and desire to achieve the best possible results for her clients is exceptional.
