IPM offers both traditional and complementary medical treatments. Every patient has a different situation they want to handle so medical therapies and treatment regimens are highly variable and tailored to each specific patient. Whether you want medical testing and treatment, nutritional counseling and advice or a specialized procedure, we can ensure that you get what is most effective for your personal situation and needs.

Our highly qualified professional staff is here to help you determine your best course of treatment, based on your own health care philosophy, your physical condition and your health goals.

Come in and talk to us. We’ll listen.

We treat people of all ages, including children.

We handle acute and chronic illnesses and provide preventive and supportive care for patients who are undergoing conventional medical treatments, such as surgery or cancer treatment.

With access to both conventional and complementary therapies, we formulate programs for health that avoid the complications of drugs and surgery whenever possible.

Here at the Institute for Progressive Medicine, our doctors work with you to arrive at the best possible treatment plan—specifically tailored to your condition and needs.

Western medicine can be sophisticated, mechanical and intimidating. The hectic patterns of modern life are stressful enough without your healthcare adding to that stress. Too many healthcare professionals impersonalize the process by not spending enough effort communicating with their patients.

At IPM, we take a different approach. Initial appointments are always scheduled for a full hour. Subsequent visits are scheduled for half an hour. We don’t want you to feel rushed. We want enough time to listen to what you have to say, and to help you get the personalized attention you deserve.

We support health and manage illness with minimal use of drugs, and recommend surgery only when necessary.

Some patients decline all medications and all invasive procedures. Some patients accept recommendations for medications or procedures. Whatever your views, we will work with you.

Our aim is to inform you of all relevant medical options and help you chose the most appropriate course of action. We are expert in lifestyle changes and the adoption of life-promoting activities.

Conventional medicine tends to label all health problems as diseases, and to treat them all with chemical cures. At times the cure becomes worse than the disease.

Some alternative practitioners avoid drugs entirely, but we believe it’s important to have expertise in conventional as well as alternative therapies, and to be able to determine when drugs and surgery can be deferred, when and how drugs may be withdrawn, and when they should be employed.

We often see people respond more positively to life-style changes and targeted nutritional supplements than to an array of drugs.

Older patients, particularly those on multiple prescriptions, frequently fare better when those drugs can be reduced. Diabetes, obesity, hypertension, hyperlipidemia, osteoporosis, arthritis, fatigue, depression, irritable bowel syndrome and other digestive disorders can often be managed without drugs. Many patients with these problems have been able to reduce or discontinue drugs entirely.

Drugs and surgery may be necessary and useful, but can also be hazardous. With care, judgment, and knowledge we assist you in making the best choice.
