Dr. Timothy Herlihy at UM SJMG in Baltimore: Internal Medicine with Hospital System Continuity
Dr. Timothy Herlihy practices internal medicine through the University of Maryland St. Joseph Medical Group (UM SJMG), a primary care and specialty network affiliated with the University of Maryland Medical System. His practice handles adult preventive medicine, chronic disease management, and care coordination for patients across Baltimore and the surrounding region.
What Dr. Herlihy's Practice Actually Is
UM SJMG operates as a hospital-affiliated medical group within the University of Maryland system, which includes University of Maryland Medical Center (the system's flagship hospital) and several regional facilities. Dr. Herlihy's internal medicine practice is a gatekeeper model: patients establish care with him for ongoing medical management, and he refers to specialists and coordinates with the broader UM system when needed. This affiliation matters for Baltimore patients because appointments, test results, and hospital records move more seamlessly within the same electronic system, and specialist referrals stay within UM's network unless a patient's insurance or condition requires an outside provider.
Services and Appointment Access
UM SJMG Dr. Herlihy's practice provides core internal medicine services: annual physical exams, management of chronic conditions (hypertension, diabetes, hyperlipidemia), acute and urgent office visits, preventive screenings, and medication management. The practice accepts most major insurance plans, including Medicare, Medicaid, Aetna, CareFirst BlueCross BlueShield, and Cigna; verification is necessary for specific plan details and out-of-pocket costs. New-patient appointments typically require a referral from your insurance or current primary care provider, depending on your plan. Wait times for routine new-patient visits generally run 2 to 4 weeks; urgent same-week visits may be available depending on schedule. The practice does not operate a walk-in clinic; all visits are appointment-based.
How Dr. Herlihy Compares to Other Baltimore Primary Care Options
Baltimore has competing primary care networks. CareFirst's affiliated practices (including those at Mercy Medical Center and Sinai Hospital) operate a similar model with local hospital continuity, though Mercy and Sinai are separate hospital systems with their own specialist networks and electronic records. Johns Hopkins Medicine operates its own primary care network with stronger research and specialty depth if you need complex subspecialty care but a larger, more institutional feel. Independent primary care practices (unaffiliated with a hospital system) are less common in Baltimore but offer smaller, sometimes more flexible practices; they typically refer out to specialists and may not have automated hospital coordination. UM SJMG sits in the middle: system affiliation ensures smooth internal referrals and hospital access, but the University of Maryland system's geographic reach is tighter than Johns Hopkins' and less comprehensive than CareFirst's breadth across the region.
Choose Dr. Herlihy and UM SJMG if you want primary care rooted in a single coordinated system with straightforward access to University of Maryland specialists and hospitals. Choose an independent practice if you prefer smaller-practice continuity and flexibility. Choose Johns Hopkins if you anticipate complex specialist referrals or have insurance that prioritizes their network.
Who This Practice Suits and Does Not Suit
This practice suits Baltimore residents (or nearby) who are established in the University of Maryland system or whose insurance includes UM providers without high out-of-pocket costs. It works well for patients with multiple chronic conditions who benefit from coordinated care and for those who anticipate hospital admission and prefer same-system continuity. It does not suit patients whose insurance does not include UM SJMG without substantial out-of-pocket expense; verify network status before scheduling. It is not suitable for patients seeking walk-in urgent care; for that, CareFirst Urgent Care or standalone urgent care centers are better options.
What a First Visit Involves
New patients complete standard intake paperwork covering medical history, current medications, family history, and insurance information. The first visit typically lasts 30 to 45 minutes and includes a physical exam, baseline vital signs, and discussion of preventive care (screenings, vaccines) and any current concerns. Dr. Herlihy or his team will establish your baseline and explain how referrals and specialist coordination work within UM SJMG. Bring your insurance card, a list of current medications, and a list of questions. If you have recent records from another provider, request them in advance to speed the process.
Hours, Location, and Parking
UM SJMG has multiple Baltimore-area locations. Dr. Herlihy's specific location and hours change; confirm the address and schedule directly through the UM patient portal or by calling your insurance provider's referral line. Most UM SJMG primary care practices operate Monday to Friday, with limited Saturday availability. Parking varies by location; hospital-affiliated offices typically offer free or validated parking.
Dr. Herlihy's practice earns its place in a Baltimore guide because it represents the most common primary care pathway for insured Baltimore adults and demonstrates how hospital-system affiliation shapes local medical continuity.
