Dr. Harrington

"I recently had ascending aortic aneurysm repair and aortic valve replacement. Dr. Harrington is very relatable and made sure I understood whatever I needed to know about the procedure. She was extremely helpful when it came time for the procedure. The surgery went so well I can't complain about anything and would do it again(if I had to😉). I have heard people have issues with the way the sternum is repaired. Right after surgery mine felt solid and well put together. I have had no issues with movement or pain. Thank you Dr. Harrington."

"Dr. Harrington did an OUTSTANDING job with my surgery. We met a few days before the procedure to discuss the process and what I should expect. The entire process was as smooth as she explained from check-in to check-out. The staff was great... Recovery was a snap and I was thrilled when I went in for my surgery follow-up appointment and she gave me 2 thumbs up. A great Cardiologist (Dr. David Brown), a great Surgeon (Dr. Katherine Harrington), a great team of recovery specialists (Nurses & Techs) are the winning combination that got me up and running again... A Team I can HIGHLY Recommend..."
