Samuel R. Williams M.D. and Lisa Williams Petit M.D. in Baltimore: A Two-Pediatrician Practice in Canton

Samuel R. Williams M.D. and Lisa Williams Petit M.D. operate a pediatric practice serving Baltimore families from an office in the Canton neighborhood, offering well-child care, acute illness treatment, and routine preventive services for infants through adolescents.

What the practice is

This is a two-physician pediatric practice rather than a large multi-specialty group or pediatric hospital system. Both physicians are board-certified in pediatrics and share clinical responsibilities across a general pediatric caseload. The practice handles standard pediatric care: well visits, immunizations, ear infections, sore throats, minor injuries, and asthma management. It does not provide sub-specialty services (allergy, cardiology, gastroenterology) in-house; those referrals go to outside specialists. The practice accepts most major Baltimore insurance plans including CareFirst, Cigna, and United Healthcare; verify coverage before scheduling, as some plans require referrals for specialist care.

Typical first visit and what to expect

New patients are usually scheduled with intake appointments lasting 30 to 45 minutes. You will complete forms covering birth history, prior medical records, immunization records, and current medications or supplements. Bring the child's insurance card and photo ID. The physician performs a full physical exam, reviews growth curves, administers any due vaccines, and discusses developmental milestones or parental concerns. If the child has seen another pediatrician before, request that your prior records be transferred at least a week ahead; this avoids duplicate testing and ensures the physician has the complete history.

Insurance, costs, and payment

Office visit copays depend on your plan but typically range from $15 to $50 for established patients; new-patient visits may cost slightly more. Well-child visits at certain ages (newborn, 2 months, 4 months, 6 months, 9 months, 12 months, 15 months, 18 months, 24 months, 3 years, 4 years, 5 years) are fully covered under most insurance plans with no copay if billed as preventive care. Acute-visit copays apply to sick appointments. Immunizations are covered at no cost when billed through your insurance as preventive care. The practice bills your insurance directly; ask about payment plans if you have an out-of-pocket balance after insurance processing.

How it compares to other Baltimore pediatric options

A two-physician practice differs from larger pediatric groups like those at Johns Hopkins pediatrics clinics or University of Maryland Medical Center's pediatric departments. Those hospital-based systems offer sub-specialty care on-site, faster referrals to specialists, and sometimes more flexible scheduling with extended hours and multiple locations. They suit families with complex medical needs, children with chronic conditions, or those seeking one-stop-shop care.

Williams and Petit's practice suits families seeking continuity with the same or one of two known physicians, shorter wait times in the office, and direct access to the doctors' thinking on common childhood issues. Hospital systems may have longer appointment waits during busy seasons because of higher volume. Smaller practices like this one can be easier to reach on the phone for quick clinical questions.

If your child has asthma, food allergies, or other chronic conditions requiring frequent specialist input, a hospital-based pediatric program with in-house allergists or gastroenterologists may reduce coordination hassles. For routine care and straightforward illness, either model works, and the choice often comes down to provider continuity and scheduling convenience.

Who this practice suits and who it does not

This practice is ideal for healthy children who need preventive care, routine vaccinations, and management of common acute illnesses (colds, ear infections, strep throat). It suits parents who prefer knowing their child's doctor by name and having a personal relationship with the pediatrician. It works well for first-time parents seeking accessible guidance on development and feeding.

It does not suit families whose child has complex, multi-system needs (severe asthma, diabetes, heart conditions, developmental delay) without support from multiple specialists, as the practice will refer out for everything beyond general pediatrics. Children with behavioral or developmental concerns benefit from practices with on-site child psychology or developmental pediatrics, which this practice does not provide.

Hours, parking, and logistics

The practice is located in Canton, a neighborhood accessible from most Baltimore city and county addresses. Verify current hours by phone or website, as pediatric practices sometimes adjust schedules seasonally or for provider availability. Street and lot parking are available in the Canton commercial area; confirm with the office whether free or paid. The office is open for sick visits and well-child visits during standard business hours; after-hours calls are typically answered by an answering service or connected to an on-call provider.

This practice offers continuity, accessibility, and board-certified care in a two-physician model that prioritizes direct relationships between families and their pediatricians, making it a solid choice for Baltimore families seeking straightforward, reliable pediatric care without the scale of a hospital system.
