You will NOT find a better attorney then Jac Knust
Jac Knust is by far the best attorney you could ever have the pleasure of working with. He is fair, honest, and hardworking. Jac represented me in a custody case and did an excellent job. When the case got turbulent, I could sleep a little easier at night knowing that Jac was doing all he could do to ensure a good outcome for me. His firm offered good and sound advice each step of the way. During court appearances, Jac was always on time and prepared. His courtroom presentation was excellent and I was very comfortable knowing he was there with me. In closing, if you are looking for a great attorney that you can trust and will work hard for you, contact Jac Knust. You will not regret it.

Helpful service
I had a consult with Jac from The Collaborative Law Group. I found that their office is responsive to calls, texts and emails. Scheduling was convenient and easy. I found the information from the consult to be very helpful and I could tell the lawyer was prepared and read over my case before meeting. Answered all of my questions and was personable / easy to talk to.

Jac E Knust is an effective, professional, and reliable attorney
We appreciate the excellent work Jac did as our attorney. Mr. Knust is extremely professional and caring. He consistently responded to our inquiries timely, and his attention to detail meant a lot to us. Jac's legal expertise and professionalism exceeded our expectations throughout our case.

Jac is extremely experienced lawyer. He doesn't treat you as a case or buisness interaction. He listens to you and cares about you. He doesn't try to do unnecessary work thus keeping the cost at the lower end. Additionally, he is extremely generous with his knowledge and time. I was impressed by how much he cared about my financial situation. Absolutely I would recommend him!

I have used Jac for several different cases and each case he was always pleasant. Jac & his staff are very professional and easy to work with. They explained things to me so that I could understand what was going on with my case. I would highly recommend him and If I ever need a lawyer again, It will be Jac Knust.
Response from Jac Knust February 21, 2016
Joan is a great client, seeks a good legal response, and appreciates our input. She is a valued client.

Used Jac for 15 minute phone session
I was basically freaking out about a potential case that could be brought against me and Jac very calmly told me all the facts and reassured me of the unlikely potential consequences. What made it even better was that he offered his services just in case things did go bad. Couldn't have asked for a better consult.

Great lawyer and a great team to match
I used the collaborative law firm after being sued by a plumber unjustly. Jac was able to quickly, fairly and justly handle the resolution with very little involvement from me. After discussing what he believed to be my best options, I was confident I had contacted the right person. I think what I liked the most was his ability to relate to me and not overwhelm me with legal jargon. The case was resolved very quickly and I was very happy with the outcome. I highly recommend Jac Knust and his wonderful staff to anyone that needs a great lawyer.

Outstanding Legal Representation
The Collaborative Law Group has handled several legal matters for me over the years, including family matters, business matters, medical, and estate planning matters. Jac Knust, Ellen Stewart, and Sarah Karalevicz are experienced, knowledgeable, and highly competent attorneys who were supportive, compassionate, and attentive to my needs. They involved me in the decision-making process regarding the resolution of my legal issues and were prompt in providing feedback to any questions I might have. They were hard-working, efficient, dependable, well-prepared, honest and fair. I highly recommend their legal services.
