    An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
    These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.

I thought at first that this doctor would be good with me. He was relaxed. But he showed little interest in talking with me about my illness. The last straw was when I was sedated just before a colonoscopy, he started a conversation about my daily medication. I was already totally out of it. STRANGE. I am DONE with this guy!

One Star

I totally agree with the previous reviewer. Dr. Mozwecz was abrupt with me too. He did not want to deal with my medical issues even though they were within his area of specialization. Did not give any recommendations. So disappointing! If he does not care about his patients, then why doesn't he get retired?! I am done with old, cranky doctors!!! The staff was unfriendly and dull. No greetings, no smile. Horrible customer manners!

Dr. Mozwecz was very condescending and abrupt with me. He didn't seem to care that what he was telling me might affect my life, and was rather rude. His office staff and nurse were wonderful, they should give him some lessons in caring about a patient.
