Our approach to healing

     If you are looking for more than just a pill for symptom relief Dr. Detweiler will test for the root cause and treat it to get you well. He believes in holistic care, and will spend the time to listen to your concerns and review previous testing so as to not repeat it.
     Then the doctor will analyze your symptoms and explain the likely causes, decide with you on what testing should be done and what treatments to undertake.
     Dr. Detweiler knows that prescription medications are often necessary but commonly are associated with undesirable consequences as well.  To minimize this he can recommend other ways to heal that include diet changes, supplements and natural medicines.
     Dr. Detweiler is a physician who listens to you and spends time with you.  He will not ask you to undergo tests that are not needed. He believes that healing you, not just relieving symptoms, is the best approach.
     Your care will always be customized to your needs, reflecting what you feel works for you, your results of past treatments, diet history, and family medical history. He will work with your other healthcare providers to coordinate your treatment on all levels from your primary care physician to nontraditional healers, ensuring you get top quality care.
     Due to his variety of medical experience he has had the opportunity to provide additional relief or healing to many patients who have been intolerant or unsuccessful with other treatment methods.
     Dr. Detweiler believes that the patient must own their healthcare and partner in decision making.
