Meet Doctor Mary Kate!


Owner- PT, DPT, OCS, C-PS, CSCS

Dr. Mary Kate specializes in treating athletes of CrossFit, softball, baseball, all field sports, and weekend warriors!

Dr. Mary Kate Geisinger has always loved sports. Growing up, she played soccer, volleyball, basketball, and softball. But in her first semester of undergrad, she sustained a shoulder injury. She underwent two surgeries and was in physical therapy on-and-off for two years. It was through this experience that Dr. MK found her passion for physical therapy.

Dr. MK graduated from Stockton University with her Doctorate of Physical Therapy in 2017. She coached travel and varsity softball at her alma mater throughout college. She obtained her Certified Strength & Conditioning Specialist (CSC) through the NCSA and became a board certified Orthopedic Clinical Specialist (OCS) in 2021. She is currently working toward her Clinical Management of the Fitness Athlete certification through ICE Physio and is interested in becoming a CrossFit Level 1 Trainer.

In her free time, Dr. MK is an avid sports fan—cheering for the Yankees, Duke Blue Devils, and NY Jets. She spends time with her family and friends, and taking early morning classes at CrossFit Arx.

About Me

  • “I cannot thank Dr. MaryKate enough for being able to diagnose issues in the past and rehabbing them back into shape for me while also giving me ways to stretch daily at home before a long work day or rough training nights in jiu jitsu. I had severe re occurring pain in my knee and within 2 months i had no pain and i had more range/flexibility. Please if you need help getting back on your feet and want the pain to go away give her your business she will give you her 110% and make you laugh in the process.”

  • “After a year of living with pain from a torn meniscus, I had arthroscopic surgery and was given a script for PT. I was amazed at the relief I experienced after the very first visit with Dr. Mary Kate. She is gentle yet firm, accommodating and encouraging.”
