About me

I am a board-certified hematologist and medical oncologist at Kaiser Permanente’s Riverside Medical Center. Here you will find information about my credentials and practice. It is my pleasure to introduce myself, and I look forward to helping support your health and well-being.

 

Biography

 

I was born, raised, and educated in Manila, Philippines. After completing my residency and fellowship training in New York City, I moved with my family to California to begin my practice at Kaiser Permanente in Riverside. The year-round mild climate of Southern California suits our easygoing lifestyle. We enjoy going to the beach, biking, skiing, and running.

 

About my practice

 

Cancer medicine is a constantly evolving field that requires a multidisciplinary approach. At Kaiser Permanente, we collaborate closely with surgeons, pharmacists, nurses, and social workers to provide comprehensive, personalized care. We hold weekly cancer conferences to discuss complex cases and develop treatment recommendations. Our goal is to address not only the disease but also the whole person — delivering care that is grounded in the latest research and evidence. In addition, we offer support groups and educational seminars to help members throughout their cancer journey.

 

Cancer Subspecialty Focus

My clinical expertise includes the treatment of skin cancers including melanoma; genitourinary cancers such as bladder, kidney, prostate, and testicular cancers; gastrointestinal cancers; breast cancer; lung cancer; thyroid and other endocrine tumors; head and neck cancers; and thymoma, as well as complex malignant and benign hematologic disorders.

 

Collaboration on Multidisciplinary Teams

I actively participate in regional multidisciplinary tumor boards that bring together experts in medical oncology, radiation oncology, surgery, pathology, and other specialties. This collaborative model helps ensure that members receive current treatments that are based on evidence and current research and aligned with national best practices — especially for complex gastrointestinal and genitourinary cancers.

 

Research and Clinical Trials Involvement

I am involved in several prestigious National Cancer Institute–supported research networks, including SWOG, the National Surgical Adjuvant Breast and Bowel Project (NSABP), the Alliance for Clinical Trials in Oncology, and NRG Oncology. As a sub-investigator on multiple clinical trials, I help bring emerging therapies to our community. I have a particular interest in cancer survivorship research, focusing on improving long-term health outcomes, minimizing treatment-related complications, and reducing the risk of cancer recurrence.

 

How I thrive

 

Preventive care, balanced nutrition, and regular exercise are foundational to a healthy lifestyle. Since joining Kaiser Permanente, running has become a powerful outlet for managing daily stressors. I have become an avid runner and have completed several marathons, including the prestigious Boston Marathon.
