D. Leonard Griffen III, MD, FACC in Baltimore: A Cardiologist Focused on Complex Heart Conditions
D. Leonard Griffen III is an independent cardiologist serving Baltimore and surrounding areas with a clinical emphasis on diagnosis and management of complex coronary and structural heart disease. He holds board certification in internal medicine and cardiology, along with the Fellow of the American College of Cardiology credential.
What Griffen Actually Does
Griffen practices as an individual cardiologist rather than as part of a larger hospital-affiliated cardiology group. His practice centers on patients with established heart conditions or significant cardiac risk factors who need direct specialist evaluation. He is not a primary-care provider and does not handle preventive cardiology for asymptomatic patients without prior cardiovascular diagnosis. His scope includes diagnostic testing interpretation, medication management, and decision-making around cardiac procedures, but he does not perform interventional procedures such as stent placement or angiography in-office.
Services and Consultation Structure
Initial cardiology consultations with Griffen typically take 45 to 60 minutes and include a detailed history, physical examination, and often integration of existing test results (EKG, imaging, labs). A consultation fee varies by insurance plan; patients with commercial coverage should expect to pay a standard cardiology specialist copay (typically $40 to $75), while uninsured patients should confirm pricing directly. Follow-up appointments run shorter and cost less.
Testing and imaging ordered during consultation, such as stress tests, echocardiograms, or advanced imaging, are billed separately and are subject to individual insurance deductibles and coinsurance. Griffen interprets these results in the context of your clinical picture rather than ordering tests reflexively.
How Griffen Compares to Other Baltimore Cardiologists
Baltimore has cardiologists across a spectrum of practice structures: large hospital-based groups affiliated with Johns Hopkins, University of Maryland Medical Center, and Mercy Medical Center; independent practitioners; and hybrid arrangements where doctors maintain privileges at multiple facilities. Griffen's value lies in his status as a high-touch independent provider with no institutional scheduling delays or administrative overhead. Hospital-based cardiologists often see more routine cases and may have shorter appointments; they also offer faster access to interventional labs and same-day coordination with inpatient services if needed. Choose Griffen if you prefer a single-provider relationship with detailed continuity and time for complex discussion; choose a hospital group if you need interventional procedures coordinated within one health system or if you want same-day urgent evaluation.
Who Griffen Suits and Who He Does Not
Griffen is best suited to established cardiac patients requiring ongoing specialist management, patients with complex multi-vessel disease or structural problems who benefit from careful medical optimization before intervention, and patients seeking a focused second opinion on treatment plans. He is not appropriate for patients needing interventional cardiology (stents, ablation, valve repair), those in acute cardiac crisis requiring emergency catheterization, or patients seeking preventive screening without prior cardiovascular diagnosis.
What a First Appointment Involves
Bring all prior cardiac imaging, test reports, and medication lists. Griffen will review your symptom timeline, prior test results, and family history in detail. He will perform a complete cardiac physical examination and discuss findings with you directly. If existing tests are recent and adequate, he may defer repeat imaging; if older or incomplete, he will order appropriate new testing. You will receive a clear summary of your diagnosis and a written plan covering medications, lifestyle, activity restrictions, and follow-up timing before you leave.
Hours, Parking, and Logistics
Griffen maintains a private practice office in Baltimore. Verify current office location, hours of operation, and parking availability by contacting his office directly, as private practices occasionally relocate. Most independent cardiology offices operate Monday through Friday during standard business hours with limited or no weekend availability; emergency cardiac issues should be directed to the nearest hospital emergency department, not to a private office.
Insurance acceptance varies; confirm your specific plan is in-network before scheduling. Many Medicare beneficiaries, Aetna, United Healthcare, and CareFirst Blue Cross Blue Shield patients report coverage; inquire about your insurer when calling to schedule.
Griffen's practice reflects the Baltimore cardiology landscape where independent specialists still operate alongside growing hospital consolidation, offering patients who value continuity and detailed discussion a real alternative to high-volume group settings.
