Dana is also an artist and enjoys painting in her free time Before joining our team, Dana was a patient of Dr. McMonagle's. She had a long history of chronic illness and extreme fatigue. For many years she was undiagnosed and very ill. At her first appointment, with coverage from her insurance, we were able to run several lab tests. Based on those results and a thorough history, we created a new treatment plan for her. This included our highly sought after Ozone treatments. Ozone was life changing for her. She began to regain energy, mental clarity and function after her first treatment. She is forever grateful for the team at Lake Oswego Health Center for restoring her health and giving her the opportunity for a normal life again. Dana is very excited to join us here at Lake Oswego Health Center. She has a passion for helping people and is excited to get to know all of our wonderful patients.

About Us

Naturopathic Medical Doctors undergo a rigorous medical education at one of the seven fully accredited North American Naturopathic Medical Schools.

The first two years of education mirror a traditional Western medical education in terms of the biological sciences: Anatomy, Physiology, Biochemistry, Pathology, Microbiology and Medical Diagnosis.

The last two years are clinical training, working hands-on with patients in a variety of clinical settings. These years focus on natural methods of healing, including nutrition, vitamin therapy, herbalism, homeopathy and physical/structural medicine, as well as Western pharmacology when indicated.

Philosophic Principles:

The Naturopathic Principles are a series of guiding ethics that form the field and philosophy of Naturopathic Medicine. They are the structure from which true health is born.

The Principles are:

  • First Do No Harm (Utilize the most natural, least invasive, and least toxic therapies.)
  • The Healing Power of Nature (Understand and enhance the body’s inherent ability to heal itself.)
  • Identify and Treat the Causes (Look beyond the symptoms to the underlying cause.)
  • The Doctor as Teacher (Educate patients in the steps to achieving and maintaining health.)
  • Treat the Whole Person (View the body as an integrated whole in all its physical and spiritual dimensions.)
  • Prevention (Focus on overall health, wellness and disease prevention.)
  • The Therapeutic Order (Choose the therapy that will most rapidly and completely bring the patient back into health.)
