Our approach is patient-centered. We emphasize counseling and education, and we work in partnership with each individual to create a unique program of primary care. At Astor Medical, we value the personal relationship between the provider and the patient. Every patient has the opportunity to choose the particular provider with whom they feel the greatest comfort, affinity and trust from among a group of qualified, dedicated clinicians.
