A safe and holistic approach to health care.

Integrative Medicine is the combination and coordination of conventional and complementary medicine. The focus is on treating the entire person and defines health as a state of complete physical, mental and social well-being. By blending the best elements of complementary medicine and lifestyle approaches with conventional Western care, the UCHealth Integrative Medicine Center – Central Park provides a safe and holistic approach to health care. We treat patients with serious diseases to optimize wellness as well as healthy patients who want to prevent disease and maintain wellness.

Conventional Western medicine focuses on specific diseases or conditions and works to find methods—many times pharmaceutical or surgical—to treat them. Typically, doctors who practice conventional medicine place the majority of their focus on the patient’s physical health.

A complement to your primary physician.

Treatment offered at the Integrative Medicine Center should be thought of as a complement to the conventional care provided by your primary care physician. While our therapies are unique and can have exciting results, they are best used alongside conventional care. Our practitioners work at their highest level when they are able to communicate openly and freely with your physician. After your health and wellness visit, a note is sent to your primary care physician.

Complementary medicine is the practice of using integrative therapies to complement conventional care.

What is a health and wellness visit?

A health and wellness visit is your introduction to the Integrative Medicine Center. A physician will discuss your questions, concerns and goals as they relate to your personal wellness and guide you through our services and self-care strategies to help you meet your health care goals. Anyone can benefit from an appointment; our therapies and lifestyle approaches can be adopted to fit a wide variety of needs. If you have an interest in maintaining or improving your health or managing a chronic illness in a safe, coordinated environment or if you have questions regarding conflicting information you’ve received about complementary medicine, please call to set up a health and wellness visit today.

Promoting self-care.

To coincide with treatment, we encourage self-care for all of our patients. It is important for patients to make lifestyle changes (exercise, nutrition, sleep, etc.) to assist in their recovery and to maintain good health. Proactive self-care will give you greater control over your health and will allow you to be less reliant on medication or other therapies.

An optimized approach to personal wellness.

The wellness and healing of the whole person—mind, body and spirit—is at the core of the vision and philosophy of the UCHealth Integrative Medicine Center – Central Park. It is our desire to draw on complementary medicine, as well as conventional Western care, to offer a holistic, comprehensive and individualized approach to personal wellness. Our goal is to dissuade patients from potentially harmful treatments and to provide truly safe and effective therapies. To best promote healing and to actively engage patients in their own health care, we encourage lifestyle approaches and self-care regimens.

What makes us unique?

The Integrative Medicine Center is the first of its kind in the region. Housed within the UCHealth Central Park Medical Center, we go beyond offering stand-alone complementary medicine services. We emphasize the importance of finding the correct balance of therapies, lifestyle changes and conventional treatments for each of our patients. Our board-certified physicians and their colleagues develop and supervise treatment plans in coordination with the patient’s current conventional care. Our professional practitioners work in concert with one another, and in full communication with the patient’s primary health care physician, to provide the safest and most effective health care possible.

Much of my work has focused on helping patients manage concerns such as chronic pain, adjustment to acute or chronic illness or disability, stress and anxiety, depression, sleep difficulties, and promoting healthy lifestyle habits. I believe it is essential to care for all aspects of ourselves – including mind, body, and spirit – and I enjoy working alongside other providers to deliver holistic, interdisciplinary care aimed at improving quality of life. I value collaboration with my patients, building upon their personal strengths while also helping them to develop new skills to learn and grow through difficult circumstances. I often integrate cognitive-behavioral therapy (CBT) and mindfulness approaches in my work, and I also have experience providing biofeedback treatment. I find my work as a health psychologist to be truly rewarding.
