Dr. Jennifer Merris

Jennifer Merris specializes in rheumatology, focusing on the diagnosis and treatment of conditions that affect the joints, muscles, and immune system. They treat patients with impaired immunity, helping those whose bodies struggle to fight off infections or maintain proper immune function. Rheumatoid arthritis is another area of expertise, where they care for patients experiencing joint inflammation and pain caused by the body's immune system attacking healthy tissues. They also provide treatment for osteoarthritis, supporting patients dealing with joint wear and cartilage breakdown that commonly occurs with aging.

Jennifer Merris practices at Penn State Milton S. Hershey Medical Center in Hershey, Pennsylvania, and maintains an additional location in Lancaster, Pennsylvania. They utilize blood tests and complete blood counts to help diagnose and monitor various rheumatologic conditions. White blood cell differential testing is another diagnostic tool they employ to better understand …how a patient's immune system is functioning. These laboratory assessments help them develop personalized treatment plans for each patient's specific rheumatologic needs.
