“Dr. Ponnaganti is one of those dental professionals that take their time and devise the best plan for her patients. The front desk always greets you with ‘happy smiles’ while she manages the phones and scheduling. The dental hygienists are organized, their rooms are super clean, and they communicate well with the doctor. This professional staff are a reflection of how teamwork works! Amazing group of caring professionals. Dr. Ponnaganti of the Westchase office in Tampa comes with my highest recommendations.”
