Unger Primary Care Concierge in Rancho Cucamonga, California

We put your family’s health and well-being first.

Welcome to Unger Primary Care Concierge

Dr. Unger always tells his patients, “I did not go to medical school to learn how to take care of runny noses. I went there to become efficient at diagnosing and treating the most complex of all medical problems.” Thus, Dr. Unger prides himself on managing patients with substance abuse disorder (alcohol, stimulants, benzos, hallucinogens, marijuana, opioids and fentanyl), type 1 and type 2 diabetes, bipolar disorder, Cushing’s disease, chronic kidney disease, chronic pain, headaches, bipolar disorder, narcolepsy, sleep apnea, and obesity.

Interestingly, Dr. Unger also teaches family medicine to UC Riverside medical students. After his first day in the office with Dr. Unger in tow, our current student said, “Wow, I never knew that family doctors can fix all these patients!” The more challenging the problem the more enjoyment Dr. Unger gets from helping that individual.

During his residency program, Dr. Unger was always challenged to come up with a differential diagnosis for every patient evaluated in the hospital. Just because you know that a patient has appendicitis, we were always asked, “OK, we know what the patient has, but what else could be causing this patient’s abdominal discomfort?”

Dr. Unger was also taught the art of listening and physically examining patients BEFORE ordering fancy tests or referring patients to other specialists. Thus, 95 % of all our patients are managed only by Dr. Unger.
