Testimonial Quotes from Bill Gentry’s book, “I Want Out”

“I’ve known and worked closely with Bill for years, and one word best characterizes him: service. I Want Out captures perfectly Bill’s dedication to serving others by relaying how he has helped client after client navigate the divorce process, and more often than not, come out better on the other side of it. It is Bill’s service-first perspective that makes him such a capable lawyer, and it is what should draw any woman considering divorce to this book.” 

Darrell L. Sutton, owner of Sutton Law Group LLC and president of the State Bar of Georgia 2019-20

“Using his years of experience, his extensive knowledge of the law, and his compassion for his clients, Bill Gentry has created a masterful book which will be invaluable to women going through a most challenging and painful time. This book provides insight into the law in a positive, encouraging manner. You will want him on your team; he dies not disappoint.”

Janet “Janel” Wiles, partner at Wiles & Wiles LLP, and John J. Wiles former Georgia legislator and managing partner at Wiles & Wiles LLP

“I have known Bill Gentry for more than 35 years and have had the pleasure of Bill appearing in front of me on hundreds of occasions. He is always prepared to zealously advocate for his family law clients. In his book I Want Out, he outlines the divorce process from a woman’s perspective in the state of Georgia. I believe this book will assist women to navigate the divorce process in Georgia.”

Retired Superior Court Judge Robert E. Flournoy III, Cobb Judicial Circuit, state of Georgia

“Whether you are a working woman who is the breadwinner of your family, or a stay-home mom (CEO of your household), this book is for you. No woman should have to worry about her future just because her husband did not hold up his end of the agreement. If your husband has told you will be left with nothing if you leave, don’t fall for it. Bill Gentry won’t let that happen. Take the first step and read this book. Knowledge is power.”

Phyllis Collins, owner and operator of Phyllis Law

“I have known Bill Gentry for 40 years. I was a mentor in his early career and have watched him develop as a leader or the organized bar and as one of the leading divorce lawyers in Georgia. Bill has written a book, I Want Out, that answers questions that a person has when she faces a divorce. I highly recommend this book.”

Harold T. “Hal” Daniel, Jr., president, State Bar of Georgia 1994-95
