Primary Care
Primary care is the foundation of lifelong health, and at our internal medicine practice, we provide comprehensive, patient-centered care for adults of all ages. Internists specialize in diagnosing, treating, and preventing a wide range of conditions, from chronic illnesses like diabetes and hypertension to acute concerns such as infections and injuries. By choosing an internist for primary care, patients benefit from a physician who not only treats immediate health concerns but also takes a proactive approach to long-term wellness, ensuring continuity of care and a deeper understanding of their overall health history.
Comprehensive Care
Internists specialize in preventive medicine, focusing on keeping patients healthy through proactive screenings, lifestyle counseling, and early disease detection. By conducting routine exams, monitoring risk factors, and providing personalized wellness plans, internists help patients prevent chronic conditions such as heart disease, diabetes, and hypertension before they develop or progress. Their approach to comprehensive care includes vaccinations, nutrition guidance, mental health support, and managing multiple conditions with a coordinated treatment strategy.
Vaccines
At our internal medicine practice, we prioritize convenience and comprehensive care by offering an on-site laboratory and vaccine administration. Our in-house lab allows for quick and accurate diagnostic testing, reducing wait times and ensuring timely treatment decisions. Whether you need routine blood work, specialized screenings, or urgent diagnostic tests, our team is equipped to provide efficient results. With these services available in one location, we make it easier than ever to manage your health with the personalized attention you deserve – a core tenant for our private practice.

Quality Medical Care
Alpharetta Internal Medicine was formed over 30 years ago in Roswell, GA, then expanded our services to Cumming, GA with the addition of Cumming Internal Medicine.
Many of the patients who started coming to our private practice in 1999 for their primary care still come to us today for their healthcare. We, of course, enjoy meeting new faces each year as well and adding to our patient community.
We continue to maintain our quality care by offering a unique approach to patient care by utilizing the latest, most effective medical treatments, combined with old fashioned concern and respect for the patient as an individual and their overall well-being.
