A Treatment Plan that Fits Your Whole Life Style

We Specializing In You


As an update to the growing concerns regarding Corona Virus (COVID-19), we would like to inform you of the steps we are taking to ensure your safety and the safety of our staff when visiting THOCPA.

We are asking the following of patients:

If you, members of your household, or recent contacts have had a fever, cough, sore throat, runny nose, or other respiratory symptoms please do not come into the office. Please call to arrange a reschedule.

If you have traveled in the past two weeks to a foreign country, please do not come into the office. Please call to arrange a reschedule.

As always, if you would like to avoid time in the waiting room, you may print and complete the necessary paperwork from our website and bring photocopies of your driver’s license and both sides of your insurance card.

We are also asking patients to avoid bringing guests or children with them to their appointments, except in cases where it is necessary to bring a caregiver.

Efforts of our staff:

After each patient, we are continuing to disinfect all equipment and surfaces, as we normally would. Additionally, we are wiping down all hard surfaces - all door knobs, surfaces at the front desk, lobby, and restrooms frequently throughout the day.

None of our staff has recently traveled to any high-risk areas and have no respiratory symptoms or fever. All medical staff members are hand washing between patients and front desk staff are hand washing and using hand sanitizer.

If a THOCPA employee was to come in contact with someone with symptoms, or develop any symptom themselves, they are directed to stay home.

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.

"I highly recommend Dr Birenbaum for anyone who has cancer."
Rebecca Crabb
