Alexander J Tiemeier, DO

Care Philosophy

Patients and their goals will always come first. Through open communication and shared decision making, patients will play an active role in their care by discussing all available options with the primary goal being to reduce symptoms and maximize quality of life. It is my belief that fostering a collaborative relationship between patients, families, and providers ensures care plans deliver not just treatment, but care that truly makes a difference.
