What Our Clients Say

“I had a very good experience with Mr. Mangum. He took the time to sit with me to discuss my case, gave me his honest opinion, and pursued my case as if he was my family member. He made me feel like he was truly on my side. When I encounter anyone, who feels they need a lawyer to protect their professional license or needs a healthcare lawyer to have their back-due to administrative injustice, I would refer them to him. With great appreciation for Mr. Mangum, I hope I never need him again. However, if I do he will always be the first healthcare lawyer I will call.”
