    Tammy has been a saving grace for me. She makes me feel so comfortable and at ease. She never rushes through our appointments and always makes sure to take her time and that all questions are answered. She genuinely cares about me as a patient and person, I'm so grateful to have found her.

    I've been coming to Dr. Merkle for over 12 years, since we moved here. My wife, son, daughter in law and and grandson go there. Always treated well.

    I lived for 20 years in another state & had never had the excellent care & treatment that I had in my first appointment with Tammy. She is excellent. I'm really lucky I get to go to this practice.
