Dr. Lager worked as an interventional cardiologist for 20 years and has performed over 10,000 cardiac catheterizations. He has served as a national proctor for Abbott and Medtronic, training physicians from around the nation how to perform the transradial wrist approach for catheterization. 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. He then completed a general cardiology and interventional cardiology fellowship at Beth Israel Deaconess Medical Center as well as a fellowship in vascular medicine at St. Elizabeth’s Hospital of Boston. Throughout his fellowship training, Dr. Lager served as Clinical Instructor at Harvard Medical School. Dr. Lager appreciates referrals from physicians and hospital centers for patients  with all types of cardiac problems, including coronary artery disease,  hypertension and cholesterol disorders. 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.”
