Committed to helping our patients achieve their health goals.
Our internal medicine practice has been proudly serving the Howard County community for over 25 years. The doctors of Charter Internal Medicine have been actively serving our patients and community with great satisfaction and enthusiasm. We share the same core values of putting our patients first and providing the highest quality of care possible.
Our Approach
At Charter Internal Medicine, we believe healthcare should be personal, proactive, and rooted in partnership. We practice medicine the way it was meant to be: with unhurried time, genuine listening, and a commitment to understanding you as a whole person, not just your symptoms or lab numbers. By intentionally limiting our patient panel, we restore the trusted doctor-patient relationship that modern healthcare often loses amid high volume and administrative burdens.
Why Our Patients Love Us
“My husband and I have been patients for more than 20 years. I cannot imagine a more knowledgeable, available and caring physician. I have recommended him to several friends, all of whom are as pleased with him and his staff.”
“Dr. Riesett is awesome and incredibly responsive. He is extremely knowledgeable and caring doctor. He has supported me thru a number of major health events while on travel, coordinating care for me with local physicians and acting as a quarterback for the treatment provided which was a great relief to my wife under those circumstances.”
“I have been a patient of Dr. Fish for about 3 years. He is a patient and caring provider that has directed my care very well. His staff is responsive and easy to work with. I am able to get an appointment quickly and enjoy chatting with his staff.”
“Dr. Fish is the best. I would recommend anyone to avail themselves of his MDVIP practice. It is more than worth it, especially with the difficulties in procuring appointments and medications in the normal healthcare system.”
“Dr. Riesett and his staff are amazing. There are extremely attentive when I call or text and respond with support and/or assist with what I need.”
“Would not be more pleased with Dr. Riesett and his staff. They are very responsive to my needs. I have been going to this practice many years and am very happy to be a patient of Dr. Riesett.”
