Cook & Siu PC
INTERNAL MEDICINE &
Proudly Serving Washington, DC, Maryland, and Virginia areas
Cook & Siu PC is an Internal Medicine and Women’s Health Group that has been providing patient care to the Southern Maryland area since 2005. Under the direction of Drs. Richard E. Cook and Betty B. Siu, this private practice has become a cornerstone for excellence in patient care and satisfaction. With smaller patient numbers and longer patient visits, we are able to focus on the details that keep our patients healthy. Both of our physicians were trained locally at nationally ranked top 100 hospitals, and have relationships with the local top academic institutions should the need arise to refer out for more serious medical problems.
The majority of our patients come from word of mouth or positive feedback from online portals. We feel this is because of a reputation that has been built over time through excellent patient care, trust, and a caring bedside manner. Thus, with the newest in diagnostic technology, a friendly staff, and well-trained physicians who are constantly keeping up with the latest medical literature through medical school/hospital lectures and the latest medical journals, Cook & Siu PC has become one of the top practices in the Southern Maryland region. Cook & Siu are also the proud team physicians for the Southern Maryland Blue Crabs.
