Jason Johnson, DO

Jason Johnson, DO, FACS, FASMBS

Program Director, General Surgery Residency Program
Medical Director - Trauma and General Surgery 

Dr. Johnson was born in North Carolina, but raised in Broomfield, Colorado. He earned a bachelor’s degree in chemistry from East Carolina University in Greenville, North Carolina. He then earned his medical degree from the University of Health Sciences College of Osteopathic Medicine in Kansas City, Missouri. He went on to complete a general surgery residency at Spartanburg Regional Healthcare System in Spartanburg, South Carolina followed by a laparoscopic and bariatric surgery fellowship at Virginia Commonwealth University in Richmond, Virginia.

Dr. Johnson’s original plan was to go into the Air Force and become a pilot. However, in high school, his mother, who was the director of medical staff at a local medical center at the time, gave Jason the opportunity to shadow a surgeon for a day. Ever since that day, he knew he wanted to go into the medical field.

“I believe in a holistic, patient-centered approach.” Dr. Johnson loves being able to help his patients get back to their daily routine in a relatively short amount of time.

While Dr. Johnson is trained in all areas of general surgery, his areas of clinical interest include:

  • Bariatric and weight loss surgery
  • Minimally invasive and robotic surgery
  • Surgical education

When he is not at work, Dr. Johnson enjoys spending time with his wife and their three children doing outdoor activities such as skiing and fly fishing, as well as going to baseball games to cheer on the Colorado Rockies.


Wendy Peterson, MD, FACS

Assistant  Program Director, General Surgery Residency Program  

Dr. Peterson was raised in Lincoln, Nebraska. She earned a bachelor’s degree in chemistry from Loyola University in Chicago, Illinois, followed by her medical degree from the University of Nebraska College of Medicine in Omaha. After earning her medical degree, Dr. Peterson completed a general surgery residency at the University of California San Francisco-Fresno.

With her father being a plastic surgeon, Dr. Peterson was exposed to surgery from an early age. Becoming a surgeon herself was something she always had interest in and the pursuit was a natural progression for her. In fact, she got the chance to operate alongside her father during her medical school training. 

Surgery can be a scary time for both the patient and the family. As such, Dr. Peterson’s philosophy is simple, “I treat every patient as if they were my own family member.”

While Dr. Peterson is trained in all areas of general surgery, her areas of clinical interest include:

  • Endocrine surgery (thyroid, parathyroid and adrenal glands)
  • Hernia and abdominal wall reconstruction
  • Alimentary tract (small bowel and colon)
  • Minimally invasive and robotic surgery

When she is not at work, Dr. Peterson enjoys spending time with her husband and two children as well as outdoor activities such as running, snowboarding and mountain biking.

Muratore SydneySydne Muratore, MD

Faculty, General Surgery Residency Program
Medical Student Clerkship Director

Sydne Muratore was born and raised in Hulett, Wyoming. She grew up on a cattle ranch, which she acknowledges instilled an early work ethic and a dedication to "something greater than oneself." She circuitously developed an interest in surgery due, in part, to the collective traits she acquired from her formative years. "Working with my hands, fixing things on the ranch, thinking about the bigger picture all came from my father. Curiosity, creativity, and the fluidity of the arts came from my mother." She went on to earn a Bachelor of Science in Biology with a minor in Leadership from Dickinson State University in North Dakota. She then earned her medical degree from the University of Colorado School of Medicine in Denver. Subsequently, Dr. Muratore moved to Minneapolis, Minnesota to complete her general surgery residency at the University of Minnesota where she also engaged in two years of clinical research. Her research there spanned perioperative infection and sepsis identification and reduction, total pancreatectomy islet autotransplantation for chronic pancreatitis, medical student surgical education, and clinical outcomes in trauma/critical care. 

Moving back to Colorado was a natural choice for Dr. Muratore. She and her husband met while in medical training here in Colorado, and it has always felt like home to them. She says SCL Health drew her "because of the juxtaposition of being able to help both medically complex patients as well as the opportunity to care for the underserved." Growing up in a rural area, she brought with her an early interest in access to care issues. Throughout her training, she has developed a passion for caring for patients from all walks of life. She has been on numerous surgical brigades to Latin America as a result. These collective experiences have taught her great respect for the art and science of surgery and it's impact on her patients' lives. "Each day, I realize what a privilege we have as physicians that patients choose to let us take care of them and put their trust in us in their most vulnerable moments. I believe in empowering my patients through education about their condition and choices, and helping guide them through the surgery process."

While Dr. Muratore is trained in all areas of general surgery, her areas of clinical interest include:

  • Acute care surgery
  • Hernia and abdominal wall reconstruction
  • Alimentary tract (small bowel and colon)
  • Minimally invasive surgery
  • Breast care
  • Surgical education
  • Perioperative quality improvement

When she is not at work, Dr. Muratore likes to enjoy everything the beautiful Colorado outdoors has to offer, namely: hiking, skiing, and landscape photography. She also tries to find time to explore the world with her husband and young daughter.

Dr. Ciocchetti has always wanted to use her knowledge, work ethic and skills to improve the quality of life for others. “It is my honor and privilege to assist my patients and their families. Most days, I am meeting someone on the worst day of their life. The ability to fix life-threatening problems and then assist my patients in getting back to their daily routine is what I love about being a surgeon.  It lines up exactly with my values: to make the world a little bit better by the end of the day than it was when I got out of bed that morning.”

While Dr. Ciocchetti is trained in all areas of general surgery, her areas of clinical interest include:

  • Acute care surgery
  • Venous insufficiency
  • Breast cancer
  • Complex abdominal wall reconstruction
