About Our Providers—Utah Hemorrhoid Specialists

Our Providers

Andrew Heiner, MD

“After decades of practicing GI medicine, what I enjoy most is that I’m able to achieve my goal of providing meaningful help to people in need. Quite often, people are surprised that relief and improvement in their quality of life are achievable. In my experience, most people can see significant improvement in their GI symptoms. But providing that difference means being dedicated to doing things as well as they can be done. I approach every person who puts their trust in me as I would a loved one. I pay attention to the details. I help put them at ease. And I truly listen. Experience has shown me that patients will almost always tell me enough to make an accurate diagnosis, which is where medical excellence — and appropriate and successful care — begin.”

R. Kyle Barnett, MD

“Gastroenterologists face a number of challenges in their daily routine, and that certainly contributed to my wanting to become a GI specialist. I enjoy a good challenge… and the rewards of being able to have a direct and positive impact on how people feel and on the quality of the lives they lead. For more than two decades, I’ve enjoyed what I do. A big part of this is knowing that it is important and does make a difference, which is why I strive always to provide the very highest level of care for each and every person I see. I try to understand what each individual is dealing with. Then I start building a relationship of trust and genuine compassion. The best care and outcomes depend on both physician and patient being personally invested in making sure things are done thoroughly, conscientiously and correctly.”

Christopher S. Cutler, MD

Your digestive health is a vital component of your overall health, comfort, and physical and mental well-being. Whether a patient feels perfectly healthy and visits me for a screening colonoscopy or has digestive difficulties, as a Board-Certified Gastroenterologist I apply my extensive experience, training, and expertise and the most recent advances in my field to a thoughtful assessment and diagnosis of each individual. We will discuss “conventional” medical approaches and complementary “alternative” approaches to determine the best options for you. In many cases — as in screening with colonoscopy — early intervention and treatment can prevent the development of disease.
Gastroenterology is especially rewarding because my patients benefit from my knowledge, experience, and use of the latest research and technology in this quickly-evolving medical specialty. For my patients with digestive disorders, I can prescribe a course of action which provides immediate relief, often restoring patients to symptom-free, normal lives. It is gratifying for me when, several times each day, patients say to me, “If only I had known the exam (or treatment) would be this easy, I would have made an appointment with you a long time ago.”

Steven G. Desautels, MD

“I became a physician for the simple reason that I wanted to do something for others, to make a difference in their lives. With disorders of the digestive tract, people’s lives are changed in a very fundamental way. Pain. Discomfort. Irregular habits. And a wide variety of symptoms that range from unpleasant and embarrassing to disruptive and debilitating. These are people who truly need help… and an improved quality of life. This is my motivation as a physician, and it’s the commitment I make to everyone in my care.”

David Schmidt, MD

“My goal as a physician is to provide the highest quality of care to every one of my patients. There is, of course, much that goes into achieving this objective. Skill. Knowledge. Capability. And dedication. I believe the best care is that which is delivered with a genuine compassion for each person’s individual needs, health and life. For me, this starts by listening. I need to know what’s going on, how it affects you, what your concerns and sensibilities are and all the other things that are intertwined with your gastrointestinal problems. But it’s also key to being truly present and involved in your care and to being a partner in helping you get back to what’s important: living — and enjoying — your life.”

James M. Stewart, MD

“As a gastroenterologist, I believe that gastrointestinal health and well-being are critical to enjoying a healthy lifestyle, and all that Utah has to offer. After completing my gastroenterology training at the Banner Good Samaritan/ VA program in Phoenix, Arizona, I am pleased to start practicing at Granite Peaks Gastroenterology in Sandy, Utah and will be serving patients across the Wasatch Front. My special interests include colorectal cancer prevention, GERD, Inflammatory Bowel Disease, and I’ve done research in obesity-related liver disease and other gastrointestinal cancers. After losing family to gastrointestinal cancers, I am dedicated to promoting screenings for early detection of colorectal and esophageal cancer.”

Mark A. Jensen, DO

I approach medicine as a collaboration between patient and provider. Healthcare is continually becoming more personalized – one treatment does not fit all. We have multiple treatment avenues for health maintenance and disease prevention. In addition, the health insight of each patient provides a valuable resource that should not be ignored. My aim is to offer progressive care which is tailored to the specific needs of individual patients.

The most effective care is that which inhibits disease from ever becoming reality.  As a gastroenterologist, I am especially interested in colorectal cancer prevention through high-quality screening colonoscopy and the management of pre-cancerous lesions.

At the same time, the successful management of active illness is life altering. Gastroesophageal reflux disease, irritable bowel syndrome, inflammatory bowel disease, liver disease, and motility disorders can be debilitating. I am excited to assist these patients in living their lives without the restraints of gastrointestinal ailments.

May Marschner, PA-C

“As a PA working in Gastroenterology, my goal is to work with the doctors, medical staff, and our patients to help deliver the best care possible. I think there is a lot of overlap between GI and other areas of medicine, so while I focus on GI complaints, I still try to keep the big picture in mind for overall health and wellness.

“I strive to educate patients, answering their questions, and make sure they are up to date on preventative screenings, like colonoscopies. I understand gastrointestinal problems can make life challenging and can be embarrassing. My goal is to treat, manage, and ideally cure the problems patients face, all in the effort to improve their quality of life and to ‘get back on the dance floor’, as Dr. Heiner likes to say. I am fully trained in Gastroenterology, and in an ever-evolving field, I read the latest research and am in constant communication with my supervising doctors. Together, we create individualized care plans so that our patients receive the best treatment possible – and get back to enjoying life!”

Whether treating common conditions, such as heartburn, or more complicated processes, like Crohn’s disease, Scott’s patient care philosophy is the same: consider the whole patient, not just the symptoms, then find the best treatment plan for that individual. Approaching treatment from multiple angles, Scott considers medications, imaging, labs, procedures, diet, exercise, and mindfulness when developing a plan. He believes this comprehensive approach ensures the best outcomes in overall health and wellbeing.

Scott’s natural curiosity leads him to constantly investigate new research and practices in the field of gastroenterology that may benefit his patients.

A Utah native, Scott enjoys the outdoor activities that our state offers. Skiing, backpacking, camping and travel are all high on the fun list.

I am a physician assistant with over six years’ experience in GI and hepatology. I have had the opportunity to work with patients with varying levels of disease severity in both the clinic and hospital settings.

I was part of Denver’s liver transplant program, and continue to treat patients with liver disease, as well as General Gastroenterology issues.

I greatly enjoy the privilege of being welcomed into a patient’s care journey. Living with and managing chronic disease can be a significant burden for patients and caretakers.

Did you know?

Hemorrhoids have been causing us problems for thousands of years (at least). The first recorded mention of hemorrhoids dates back to Egypt in 1700 BC.


“I had two previous bad experiences... If I had known earlier I would have been in less pain for years.”

“Absolutely the best. Haven’t felt this good in years.”

“Every time a bout of hemorrhoids flared up, I knew I was in for 10 to 14 days of pain, bleeding, itching, and plenty of creams or suppositories. The procedure was not only painless but it put an instant end to my discomfort. I’m just sorry I didn’t do it sooner.”
