Hiring Mark and his firm is a good investment!
Some people say that hiring an attorney is not good investment, this is not the case when you hire Clausen law Firm PPLC. I hired Mark to help with a property damage and defective construction case. Mark and Tyler's expertise and professionalism guide me through this stressful process and put this dispute to bed!

Clausen Law Firm helped our Association through a very contentious lawsuit that involved a single plaintiff and multiple defendants. The need to build consensus among multiple defendants was conducted competently and professionally by Clausen. Despite the odds, we were able to prevail, thanks to the experience and direction provided by the Clausen Law. We would recommend them to anyone in need of their expertise.

Mark A Clausen
My name is Greg and I am a physician for 32 years and rely upon very well respected and efficient legal help when a situation requires legal intervention. I have used Mark Clausen in the past years with EXCELLENT results. I have just turned to him again in 2019 to help me with a very difficult professional contract, and he resolved the matter in a VERY TIMELY, EFFICIENT, AGGRESSIVE AND PROFESSIONAL MANNER. HE SAVED ME THOUSANDS OF DOLLARS IN WHAT WOULD HAVE BEEN A VERY UGLY CASE HAD I NOT INVOKED HIS SERVICES. I WOULD NOT USE ANYONE ELSE BUT MARK CLAUSEN FOR CONTRACTUAL MATTERS IN THE FUTURE. IGNORE WHAT ANY OTHER REVIEWS ABOUT HIM HAVE BEEN POSTED. I AM BLESSED TO HAVE HIM ON MY SIDE, REPRESENTING ME. ANYONE USING HIS SERVICES WILL BE BLESSED AS WELL. HE IS SIMPLY THE BEST AT WHAT HE DOES. PERIOD.
