Lucas is a great attorney and truly goes out of his way for his clients. He’s always honest and upfront, and he’ll recommend whatever is genuinely best for you, even if it means you don’t end up hiring him. He really knows his stuff when it comes to estate planning and probate, and he’s incredibly smart and thoughtful in the way he handles every case. You can tell he always thinks in the best interest of the client. I definitely recommend him.
