I’m now well educated, Thank You
I interviewed two attorneys and Sven is the most ethical, polite and trustworthy attorney. I paid for my consultation and became well educated. Should I move forward I know about where I will end up, should I need to pay alimony or collect it, cost of different approaches, but most of all I believe Sven’s Team will remove a lot of anxiety so I can live and be happy.

Mr. Buncher is what lawyers are suppose to be. Honest, upfront and full of integrity. He "isn't" one of these attorneys that is more worried about racking up hours instead of you and your case. I felt like my case was important to him. I have used him twice and feel lucky to have him represent me.

Very Happy Client
From the moment we spoke to Mr. Buncher and his team, we felt important. Mr. Buncher first met my husband and I in the hospital. He was able to see firsthand what we were going through. He was always very caring and forthright. We were given sound advice and support through the entire process. Going through a lawsuit is not easy nor fun, but Mr. Buncher made us fully aware and as comfortable as we could be, until we were able to settle our case. We would highly recommend him to anyone going through medical malpractice. He understands the technical terms and was able to put them in a language we could also understand. Mr. Buncher was also very resourceful and was able to find the best experts in the field who were able to make a world of difference in my husband's recovery. We are very grateful. Thanks a million and more!!! Literally!

Great attorney and Just an overall pleasant person
Sven helped guide me through a very complex personal matter. I'm a very hard person to work with. Sven is most likely the only attorney in town who could have stayed with me to the end. He really cares for his clients. He goes over and beyond the call of duty. I highly recommend. PS One thing that really stood out is Sven didn't nickel and dime me to death over every little email and short phone calls. He very honest with his case time and doesn't have so called phantom charges.

Worthy of SIX stars!
Mr. Buncher handled our recent issue in a most professional manner. He jumped right on the case and knew exactly how to proceed to achieve the results we desired in a timely manner. His knowledge, guidance and ability to settle the case is proof of his talent. He was most respectful, and helped us understand the pros and cons of our matter. Witnessing Mr. Buncher in action was fascinating! We knew we were in good hands from the first moment we contacted his office. This rating system needs another star, because Mr. Buncher deserves the accolades. We'll certainly be referring him to those who need his services.
