Cynthia Scott
"I have known and worked with Paul for many years. Whenever Paul was the lawyer on our files, we knew that the case would be handled professionally, efficiently and would he keep us informed every step of the way. There are very few lawyers that can match Paul’s hands-on legal experience in his practice areas."
Frank SchroderSafety Codes Officer
"A testimonial for Harper-Lee Overli could be pages long, like her legal career and length of her relationships. But to nail the top points, she is meticulous with her contracts, and so talented with her ability to offer out of the box thinking and solutions to complex corporate problems. Harper-Lee’s best quality though, is her humility and understanding of people, whatever the situation may be. Don’t try to match wits with her either, I’ve only ever seen her win."
Sharlene MassieFounder, About Staffing
"Working with Harper Lee and her team has been seamless. They took care of
all the details for us and understood our specific needs right from the
start. It was easy navigating the legal system with sound, concise and
superior legal advise from Harper Lee and her team. If anyone asks, I
would recommend this client-focused company without hesitation."
