Dr. Samir George Ouais is a warm, detail-oriented endocrinologist and internist treating patients in Houston and the Woodlands, Texas, and the surrounding communities. He goes into full detail when communicating with his patients and applies a goal-driven approach to treatment. He also holds certification from the American Board of Internal Medicine in internal medicine and endocrinology, diabetes, and metabolism.

Originally from Syria, Dr. Ouais attended the University of Damascus to pursue his medical degree. He received fellowship training in endocrinology at MD Anderson in Houston.

Patients visiting Dr. Ouais can receive a full range of medical care. He treats issues including diabetes, thyroid problems, hirsutism, and endocrine-related causes of infertility. When he is not treating patients, Dr. Ouais enjoys traveling and spending time with his family.

Medicine has always been part of his life. Dr. Eric Orzeck was born on the Makah Indian Reservation in Neah Bay, Washington, where his father was the only physician meeting the health care needs of the Indian tribes in the western Olympic Peninsula. The practice extended over hundreds of square miles – which he covered on horseback. Eric helped him pack the saddlebags with the instruments and medications for each day’s “house calls.”

After graduating from high school, the future Dr. Orzeck enlisted in the U S Army and was assigned to a mobile hospital unit (MASH). This experience led to his enrollment at Alfred University and early acceptance at the University of Virginia School of Medicine. He completed his Internal Medicine Residency at the University of Iowa Hospitals in Iowa City. As part of his Endocrinology training, he returned to the University of Virginia for his first year’s Fellowship. The second year was completed at the M D Anderson Tumor Institute, now the M D Anderson Cancer Center, in Houston, Texas. He is Board Certified by the American Board of Internal Medicine and was awarded Fellowship distinctions by the American College of Physicians (FACP), and the American College of Endocrinology (FACE).

In addition to his busy Houston endocrinology practice, Dr. Orzeck is actively involved as a volunteer with medical and community programs. He has returned to the Makah Reservation as an interim volunteer in their health clinic. As well, he was instrumental in obtaining grants to outfit two ambulances with patient care and communications equipment – crucial to communities separated from the nearest hospitals by more than 60 miles of challenging roads along the coastline. Back in Texas, he is certified by the West University Place Office of Senior Services as a handyman providing pro bono services to senior citizens – without cost to the community or residents. For more than two decades, Dr. Orzeck also has repaired donated medical equipment to be sent to developing countries in response to their specific requests. This local charity – Medical Bridges – is consistently rated in the top tier for their work, and they can always use volunteers: medicalbridges.org/volunteer/sort-room-volunteer

Dr. Orzeck looks forward to continuing his medical career at the Endocrine Center. After hours, he’ll be busy with his volunteer commitments…or practicing zydeco dancing (which needs more help than he’ll admit).
