Sona Bata Psychological Services (SBPS) is named in honor of a city in the Democratic Republic of the Congo (Sona Bata), where Dr. Ndombele’s father was born. The name reflects the values that guide the practice—community, connection, and a deep commitment to care and service.

This foundation shapes every aspect of our practice. At SBPS, we belief that each individual is part of a broader community and deserves to be understood, supported, and respected within that context. Clients can expect an experience that is not only professional and thorough, but also grounded in empathy, cultural awareness, and genuine care.

Our Approach

At SBPS, we take a collaborative and individualized approach to every evaluation. We combine evidence-based assessment methods with a deep understanding of each client’s unique background, experiences, and goals.

Our evaluations are intentionally designed to be comprehensive and thorough, allowing us to provide:

• Clear and accurate diagnostic insight

• Detailed, high-quality reports

• Practical, real-world recommendations

• Documentation that supports accommodations, services, and legal needs

This level of depth and attention allows us to deliver evaluations that are not only clinically sound, but highly usable and impactful across educational, professional, medical, and legal settings. Many of our clients choose this approach because it provides a more streamlined, personalized experience, with greater flexibility and a focus on delivering meaningful results in a timely manner.
