We love our clients and patients!

Thank you Dr. Waikart for your expertise while removing Zoey’s tooth. Your preparation for complications that could happen saved our girls life when her blood pressure dropped so low. We appreciate you and your staff and are so happy to have our girl sleeping comfortably next to us on the couch.
