Client Testimonials

Gerard D.

"Several years ago, not really having an attorney, I contacted Mark Fischer of High Swartz for advice regarding a complicated family estate matter. Upon meeting with Mark at High Swartz’s offices in Norristown, I was immediately impressed with his knowledge and professionalism as well as his likable demeanor. His questions regarding my legal matter were both thoughtful and on point. By the conclusion of our initial meeting, Mark was able to provide me with the direction I needed to resolve my legal matter. Throughout the entire process, Mark was instrumental in helping to bring the matter to a very successful closure. I highly recommend Attorney Mark Fischer."

Jeff K.

"High Swartz and Mark Fischer were recommended to me by another law firm to help resolve a non-compete problem with a firm that purchased my business. That recommendation alone speaks volumes about Mark and his firm I found Mark to be a more than competent partner in dealing with the problem. His knowledge of the law regarding M&A is to be respected. Mark's patience in dealing with my unreasonable detractor is admirable. We were able to form a team to work out a path to end the legal challenge that allowed me to settle the case and to resume my life without the sword of legal actions hanging over me The episode was unpleasant and unsettling from start to finish. I am happy to have had Mark Fischer and High Swartz on my side."
