Dr. Mathier and his staff could not have been nicer! He and his assistant doctor were so patient and nice. they both spent a lot of time with us going over every test I had done and what to expect going forward. Both informed us of everything we needed to do and what each step was going to be. So knowledgeable! Will recommend them to anyone who needs a good heart doctor!

The staff in the clinic are always so helpful and gracious when caring for me. From the moment Mary greets me at the reception area, to Ashlee assists with taking blood, I have a great experience. Jen and Dr. Mathier are always available to answer even the silliest questions or entertain my ideas on what might be happening and of course, I cannot leave out Laura who has the best listening skills. I appreciate this team more than I can share.
