      Dr. Patrick Bartoshyk ND

      While reflecting on his career path, Dr. Bartoshyk states “I believe my career path and practice focus were shaped by a multitude of sporting and educational opportunities that exemplified the importance of a healthy body and healthy mind. While discovering the importance of translating modern science to guide preventive and therapeutic clinical practice decisions, it became unmistakably clear that all body systems, structures, and functions are interconnected in the healing and wellness continuum.”

      My areas of focus are: 

      • Pain elimination and tissue regeneration
      • Sport and athletic performance
      • Chronic digestive dysfunction
      • Men’s health (mood imbalance, hormone decline, urogenital change)

      My passion is helping you create a life with more health, confidence & happiness, and less stress, pain & insecurity.
