 Central Minnesota Foot and Ankle doctors Greg and Karen Rau are with us. Dr. Karen, I want to ask about certification. I know that you and Dr. Greg both heavily certified. What is the importance of certification? Certification means that you've gone the extra mile to educate yourself specifically in certain areas that make you that expert so that you can give great care to your patient. And we're dual board certified, so we are experts in foot and ankle and are able to offer expertise to treat those conditions.
