In February 1949, ten local doctors and a team of nurses, technicians, and support staff opened the doors of Boulder Medical Center on the corner of Broadway and Balsam Streets in Boulder. An innovative business model for its day, this new medical community brought together the area’s top primary care and specialty care providers under one roof.

Endocrinology
Endocrinology is the study and treatment of the endocrine system, which is the network of glands and hormones that affect every process in your body. The endocrine system guides metabolism, respiration, reproduction, sensory perception, bone structure and movement.
Hypothyroidism
The thyroid gland is vital to metabolism, growth and maturation. Located at the front part of the neck and shaped like a butterfly, the thyroid helps regulate many body functions by releasing hormones into the bloodstream. If too little thyroid hormone is produced, our body can slow down. This condition is called hypothyroidism.

Ultrasound

Radiology
When you get services from an in-network hospital or ambulatory surgical center, certain providers there may be out-of-network. In these cases, the most those providers may bill you is your plan’s in-network cost-sharing amount. This applies to emergency medicine, anesthesia, pathology, radiology, laboratory, neonatology, assistant surgeon, hospitalist, or intensivist services. These providers can’t balance bill you and may not ask you to give up your protections not to be balance billed.

General Surgery
Yes, podiatric surgeons are qualified to perform surgery for bone, joint, muscle, ligament, and tendon pathology of the foot, ankle and lower leg. Levels of surgical services do vary amongst DPM’s based on their training; this is true among MD’s and DO’s as well. Some DPM’s treat only the forefoot, some focus on the rear foot and still others specialize in the entire foot and ankle. Likewise, there are general orthopedists who treat only foot and ankle and those who treat neither. Because of the large diversity in this specialty, patient research is crucial. It is advisable to inquire about a doctor’s training, to obtain references and to seek second opinions.
Orthopedics
When you experience an injury involving your spine, bones, muscles, or joints, a board-certified physiatrist can be a practical first step toward evaluation and treatment. Elise Itano, MD, board-certified physiatrist, and Aaron Stern, certified physician assistant (PA-C), are trained to pinpoint problems and provide non-operative interventions and treatments. With an orthopedics and sports medicine focus, they help patients relieve their pain, enhance performance, and regain function without surgery. They also refer to and work closely with our orthopedics team when surgical options may be appropriate.

Bunions
Vascular Surgery
A podiatrist (DPM) is a doctor with the same undergraduate prerequisites as an MD or DO physician and who attends a four-year medical school preparation in diagnosing and treating the foot, ankle, and lower leg. Orthopedic surgeons study for four years in a college or university, four years in medical school, five years in a postdoctoral residency program studying the whole body. Podiatrists study for four years in a college or university, four years in medical school, and typically 2-3 years in a postdoctoral residency program where they receive advanced training in podiatric medicine and surgery and serve clinical rotations in anesthesiology, internal medicine, pathology, radiology, vascular surgery, infectious disease, emergency medicine, and orthopedic and general surgery. The major difference is that while orthopedic surgeons are trained to operate on the entire muscle and skeletal system, podiatrists focus solely on the foot and ankle. So while an orthopedic surgeon may have a better general medical background, a podiatrist has spent more time studying the foot and ankle. DPM’s generally are better educated in regard to lower extremity anatomy, surgery, biomechanics, and bracing. DPM’s chose their specialty (foot and ankle) from day one, thus giving focus toward the specialty years before MD’s.

They are commonly referred to as ENT physicians. The ENT Department at Boulder Medical Center addresses a diverse range of issues for patients of all ages. Conditions we address include...
Ingrown Toenails
Hip Replacement
Knee Replacement
“I had a total knee replacement and my experience was great. I met with Doctor Repine before the surgery and he explained everything that was going to happen during and after the surgery. This was the first major surgery I have ever had and I was very nervous. Dr. Repine and his staff answered all my questions and were very nice, from pre-op preparations to post-op treatments. He prescribed an in-home physical therapist and she arrived the next day I was home. I think that having physical therapy right after surgery hastened my recovery. My post-op appointments were with Laura, his PA, who was also very knowledgeable and answered all my questions. I can’t say enough about my great experience with this doctor and his staff.”

Cosmetic Dermatology
Skin Cancer
Living in beautiful and sunny Boulder County, Colorado, can positively and negatively affect our health. Moderate sun exposure can bring benefits such as stronger bones, improved moods throughout the year, and a more robust immune system. However, living at a higher elevation also means that we are exposed to about 25 percent more ultraviolet radiation from the sun compared to sea level. Therefore, although we enjoy many sunny days in Colorado, knowing the increased risks of long-term high-altitude sun exposure is crucial. The sun’s ultraviolet radiation is the leading cause of skin cancer, and years of exposure can cause hyperpigmentation, thinning of the skin, and up to ninety percent of wrinkles.
Dermatology
