About Us & What We Do

The Texas Hematology Oncology Centers, PA, was established by Dennis Birenbaum, MD, in 1997. Birenbaum, along with colleague Eugene Wyszynski, DO,  bring decades of experience helping patients and their families navigate the cancer diagnosis. The medical staff offers compassion and care, and provide knowledge of cutting-edge technology and cancer therapies directly to the communities of Dallas, Plano, and McKinney. At Texas Hematology Oncology Centers, PA, service and care for patients are key. Patients have access to their own physicians, infusion nurses, and clinical nurses 24 hours a day. A clinical care team brings together all available resources to help bring patients toward remission and to make life easier and more comfortable for them and their families during a difficult time.
Support Groups
Through its growing Support Group program, sponsored by the American Cancer Society, we offer discussion, emotional support and educational programs to cancer patients and their loved ones to help them cope with cancer.
Dietary Counseling
In order to provide out patients with the ability to maintain the highest quality of life and maximize the cancer fighting capabilities of the body’s immune system, we are now offering professional nutritional consulting under the supervision of Dr. Birenbaum, thus providing your body with the best response to cancer through healthy lifestyle choices.
Our onsite laboratory provides specialized testing for oncology and hematology. The Lab’s capabilities span all types of tissue, including tumor marker tests. While patients and referring physicians benefit from the convenience of a lab within the Cancer Center, insurance contractual arrangements may require patients to use other labs, with the results sent back in a timely manner.
Financial and Insurance Counseling
While the ultimate responsibility for a financial obligation belongs to the patient or guarantor, our goal is to assist our patients and families in every way possible to maximize insurance coverage. Our business office specialists and financial counselors serve as resources for working with your insurance provider and finding answers on your behalf. We participate in Medicare, Medicaid and most managed care plans.
