"Dr. Justin Schaffer is an exceptional cardiothoracic surgeon. Having practiced as a Clinical Pharmacist for over four decades, I have worked alongside countless physicians and surgeons throughout my career. When I received the news that I needed a quadruple coronary artery bypass, my emotions were understandably overwhelming.

The surgery was a complete success, and my recovery has exceeded my expectations. I credit not only Dr. Schaffer’s remarkable surgical skill but also his dedication to providing outstanding patient care. His expertise, attention to detail, and reassuring presence made an extraordinary difference to both me and my family.

After reviewing his postoperative notes, it became even more apparent that I had made the best decision for my care. His documentation was concise, thorough, and meticulously detailed, outlining every step taken to achieve the best possible outcome. I’d also like to give kudos to the entire healthcare team whose expertise, compassion, and dedication contributed to my successful surgery and recovery.
