This is a family run business that treats their clients like family throughout the entire process – and when you’re in a stressful situation and sometimes fight for your future, family is who you lean on. Our family has leaned on them twice for personal injury cases – and will again without hesitation if ever needed again.”

“We were extremely pleased with the estate planning service provided by Growney, McKeown and Barber law office. They were very knowl-edgeable in terms of Florida statutes that may have affected our move to Florida and our present estate plan. The entire process was comfort-able, efficient and very professional.”
