H. Jürgen Lenz, MD, PhD
Dr. Lenz believes that many gastrointestinal and liver diseases can be prevented or positively influenced by a healthy life style: a healthy diet, exercise and stress reduction.

Dr. Lenz believes that the real art of medicine lies in making the correct diagnosis with the least invasive and smallest number of tests and treatment should be as natural as possible.

Dr. Lenz believes in social justice and therefore he regularly sees patients in his office from clinics that serve patients without health insurance.
