About Northeast Florida Internal Medicine
Internal Medicine & Integrative Wellness Clinic in Jacksonville, FL
Northeast Florida Internal Medicine is a family-based medical practice with a long history of expertly catering to the unique needs of every patient. At the Jacksonville, Florida, office, internal and obesity medicine specialists Elyssa Blissenbach, MD, and Lea-Anne Griffis, APRN, lead an experienced team of support staff, many of whom have been with the practice for more than a decade.
The Northeast Florida Internal Medicine team offers comprehensive internal and obesity medicine in the office, including weight loss management, preventive health care, and treatment for acute and chronic conditions that affect adults, such as Lyme disease, attention-deficit/hyperactivity disorder (ADHD), and COVID-19.
The team wants to make it as convenient as possible for their patients to get the medical care they need, so they offer telemedicine and in-person visits, including diagnostics and lab testing in-house. Patients can also get many wellness treatments in the office, like pellet hormone replacement therapy.
Northeast Florida Internal Medicine proudly offers a one-stop shop for adult medical needs and always goes the extra mile to help with everything, from routine care to complex diseases. Set up an appointment by calling the office or scheduling online today.
