About Our Dallas Cancer Treatment Center

The Texas Hematology Oncology Centers (THOCPA) was established in 1997 and together with Dr. Dennis Birenbaum and colleague Dr. Eugene Wyszynski bring their six decades of experience of helping patients and their families navigate the cancer diagnosis and treatment. The THOCPA Cancer Care medical team offers compassion, care, and provide knowledge of cutting-edge technology and cancer therapies directly to the communities of North Texas and beyond.

At THOCPA, service and care for our patients are key. Patients have access 24 hours a day to their own physicians and the clinical team is "on-call as needed". The THOCPA clinical care team brings together all available resources to help treat patients and to make life easier and more comfortable for them and their families during these difficult times.

Financial Counseling

While financial obligation of cancer treatment belongs to the patient, it is THOCPA's goal to assist our patients and families in every way possible to maximize their insurance coverage and assist them in finding the many co-pay assistance programs available today. Our business 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.


THOCPA's laboratory team provides specialized testing for oncology / hematology and has the capabilities to scan all types of tissue including advanced tumor marker tests. While patients benefit from the speed and convenience of our lab within the center, a patient's insurance contractual arrangements may require patients to use other labs with the results sent back in a timely manner.

Dietary Counseling

We offer professional nutritional consulting to our patients so that they have the ability to maintain the highest quality of life and maximize the cancer fighting capabilities of the body's immune system. By doing this, the patient's body responds best to cancer treatment through healthy lifestyle choices.

Support Groups

Through its growing Support Group program that is sponsored by the American Cancer Society, THOCPA offer discussion, emotional support and educational programs to cancer patients and their loved ones to help them cope with cancer.
