We have bittersweet news to share. Dr. Flenniken is retiring after nearly 40 years of dedicated service to Highland Clinic since 1986.
We are so thankful for his exceptional patient care and commitment to our community. Dr. Flenniken and his nurse Sarah will be sorely missed by the Internal Medicine team and all of us at Highland Clinic.
Thank you, Dr. Flenniken, for your years of service. Enjoy your well-deserved retirement! π©Ίπ
