Dr. Mathison of Catalyst Medical Center and Clinical Spa

susan mathison, md

Our Founder, Dr. Susan M. Mathison, is a Stanford-educated, triple-board certified physician. She’s received numerous accolades for leadership and Top Doctor for her clinical skills. Dr. Mathison has been the pioneer of the region, bringing Botox to Fargo over two decades ago!

While Dr. Mathison enjoys helping patients in many ways, Facial Plastic Surgery is her main focus of passion and expertise. Facial plastic surgery offers cosmetic or reconstructive medical care to the face, head, and neck. It is a specialty within the field of otolaryngology, also known as ear, nose, and throat medicine. Facial plastic surgery usually reshapes specific parts of the head and neck, including the nose, ears, chin, cheekbones, and neck or jawline. This might include:

  • Skin cancer reconstruction
  • Birthmark removal by laser or surgery
  • Brow lifts
  • Eyelid surgery
  • Facelifts
  • Rhinoplasty (nose job)
  • Lip lifts
  • Buccal fat removal
  • Plus, many non-invasive and  minimally invasive treatments like injectables, lasers and skin care.

Dr. Mathison has helped many children with facial injuries from dog bites or falls, and has done surgery for women who've suffered from domestic violence.

She is involved in several organizations in the Fargo-Moorhead community, including Dakota Medical Foundation, TedXFargo, and The Choice Financial Board.

In her own words, "I love team Catalyst because of the ‘patient centered’ care that is at the forefront of our values. You are not just a number here, that is for sure! It will be a great collaboration as Dr. Mathison adds comprehensive vein care to what Catalyst Medical already has to offer."
