Mark Fischer is a partner in the firm’s litigation department. His practice focuses on representing businesses and individuals in legal matters involving:

  • contracts (business-business, business-customer, contractor-subcontractor)
  • construction and home renovation (residential and commercial)
  • consumer protection claims
  • mortgages and liens on real estate
  • commercial leases
  • condominium and home owners associations
  • land development and zoning

Mark’s skills as an attorney center on his ability to represent the client’s best interests while maintaining a constant-eye toward efficiency and resolution. He applies a business-oriented, customer service approach toward litigation. He has developed this mindset over his several years as regional counsel to a multi-national retail company, an experience that has provided Mark a view through the eyes of in-house counsel. He uses this experience to counsel businesses on strategically handling disputes without losing focus on the business’ end goal and its bottom line.

Currently Mark serves as assistant township solicitor to Lower Macungie Township and on zoning matters for Upper Dublin Township in Pennsylvania. Mr. Fischer also has considerable experience in handling complex zoning matters on appeal to the Common Pleas and Commonwealth Court levels.

Mark is a studious attorney with an attention to detail. He finds value in the art of cooperation and collaboration with other attorneys to determine the best strategies for effectively handling his cases. He leads by example, both in his work and his personal pursuits, which has made him a productive member of the legal community. This was confirmed when he was appointed as Chair of the Montgomery County Law Reporter, a publication that contains recent opinions, local rule changes, legal notices, and the latest Montgomery Bar news.

Mark has an intimate knowledge of the Philadelphia area. He grew up in Philadelphia and Lower Bucks County, attended college and law school in Delaware County, and now lives and works in Montgomery County. This knowledge of the area gives Mark a unique understanding of the local communities and the business climate in the Greater Philadelphia area. In addition to his work in Pennsylvania, Mark has significant experience in the New Jersey Courts. He completed his judicial clerkship there following law school and now handles commercial litigation cases throughout the State.

Mark currently lives in Montgomery County with his wife, son and two daughters. He enjoys sports, exercise, exploring the local parks with his family, and rooting for his beloved Philadelphia sports teams. In his spare time you can find Mark coaching for Plymouth Little League and Colonial Soccer Club of Plymouth Meeting, PA.

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.”
