In addition, he has trained many cardiology fellows in the interventional cardiology fellowship program at MedStar Washington Hospital Center,and contributed as a clinical investigator in multiple interventional cardiology research studies involving new devices and interventional techniques

Dr. Lager specializes in conditions related to coronary artery disease, peripheral vascular disease, and structural heart disease. He also sees patients for hypertension, atrial fibrillation, and cholesterol disorders, with a strong interest in preventive cardiovascular medicine.

Dr. Lager received his medical degree from the University of Pennsylvania before completing his internship training and residency training at Massachusetts General Hospital.

When not practicing cardiology, Dr. Lager enjoys regular exercise with his family and pursues his passion for travel.

Philosophy of Care

“I live by the golden rule that I treat patients like I would treat my family members or treat myself. I have found that this simple rule has guided me along my journey to develop an empathetic and patient-centered practice.

“Patients have better outcomes when they are informed and educated. For this reason, I’m very much about communication and transparency. An educated patient is generally a healthy patient. I also ask patients to take ownership of their care and urge them to live a healthy lifestyle.

“Empathy and taking the time to listen are a big part of my practice. The history and the story that one gets by listening to the patient are as valuable as any objective testing that we do. Above all, I want each of my patients to feel that they are my only patient.”

    Dr. Lager is phenomenal!

  • Sep 22, 2024

    I was very impressed with Dr Lager. He was not only very knowledgeable but was an excellent communicator. In addition, he conveyed an empathy , that although unspoken, was perceived by me and my wife.
