very good
Dr. Hagau was wonderful. I very much so enjoyed seeing her. There was a scheduling conflict but that was not her fault.
Outstanding care and doctor.
Very short wait in waiting area, everyone was very friendly and professional, good experience.
Dr. Hagau examined heart surgery incision and discovered "stitch" that poked through the skin that was not allowing the incision to heal properly. It was clipped off and we will see if this helps the healing process.
Excellent. Short wait in lobby. On time.
