Dr. de Sieyes believes that a caring doctor-patient relationship is key to promoting preventive health and well-being. He is committed to dedicating adequate time in his appointment schedule to foster mutual trust and understanding, and recognizes the uniqueness of each patient’s needs. He also believes that his affiliation with True North will complement his own traditional approach to healing.

Dr de Sieyes has been in private practice in the greater Portland area since 1980. In addition to his work with True North, he teaches medical students and residents at the Maine Medical Center, volunteers his services at the Portland Community Free Clinic, and serves as school physician for the Falmouth and Bonny Eagle (MSAD 6) school departments. He has formerly worked as a team physician for the Maine Mariners and the Portland Pirates of the AHL, and has participated in medical projects in Haiti, Kenya, Tanzania, and Brazil.

Dr de Sieyes and his wife, Dr. Carol Ward, reside in Falmouth. They are the proud parents of two grown sons.
