A Family Practice Rooted in Community

The front room of our Castro Valley office is also the adjusting room. From the moment you enter, you become part of the community. It is a welcoming space where patients support one another, celebrate progress and heal together.

Our practice brings together Dr. Marisa Sum, Dr. Cassie Stansberry and Dr. Justin Mariano, licensed doctors of chiropractic who also serve as X-ray supervisors and technicians. Throughout the week, they perform chiropractic, orthopedic and neurological examinations, take X-rays and provide personalized adjustments.

Dr. Stephen Sum Jr., Dr. Marisa Sum’s father and the longtime owner of Eden Valley Chiropractic, also practices here during his own office hours. Kaname Castro Valley is truly a family practice, guided by a multigenerational legacy of bone setters and healers.

Our Approach to Chiropractic Care

We support the body’s ability to heal from within while considering the many physical, emotional and environmental factors that shape a person’s health.

Each patient’s care may include:

  • Musculoskeletal and neurological assessments

  • Full-spine radiographs to understand spinal alignment

  • Follow-up imaging to document measurable progress over time

  • Personalized chiropractic adjustments

  • Exercise and mobility guidance

  • Nutrition and ergonomic recommendations

  • Support for emotional stress, energetic blockages and stored trauma

  • Free educational classes about spinal health, movement and injury prevention

Our goal is not simply to manage symptoms. We help patients better understand their bodies, address underlying concerns and build the confidence to move through life with greater ease.
