    I really trust Dr. Jonklaas. She has lovely mannerisms I have recommended her to others.

  • Jan 26, 2022

    I have been seeing Dr. Jonklaas for years! I feel I am well taken care of. She is very clear in her explanations and listens carefully to questions.

    I would recommend Dr. Jonklaas w/a warning that the patient experienced at the hospital is terrible.
