Who takes care of you better than your mother? And while your mother may not be a cancer expert in your time of need, uses its patented “Mother Standard” of care that empowers each employee to provide the same care a loving mother would give to her child.

Patients come from near and far for cutting-edge treatments, including advanced forms of surgery, radiation, chemotherapy and imaging services combined with nutrition, spiritual support, mind-body medicine and naturopathic medicine.

Employees are encouraged to keep themselves healthy with a $600 annual vitamin and supplement benefit. An annual bonus program is in place for each stakeholder for meeting individual and department goals.

To further broaden the center’s reach, a Spanish-speaking initiative is in place, giving employees the opportunity to learn the language to better serve the Hispanic population.

Longevity in five-year increments is rewarded. At an annual awards dinner, those who have reached a milestone receive a certificate, a pin and a monetary bonus. Five years equals $100; 10 years equals $250; the 15-year bonus is $500; and for 20 years of service, the center cuts a check for $750.
