Dr. Ronald Poltera

Dr. Poltera and his wife moved to Winfield in 1981 and were blessed with a daughter that same year. While sharing time with his father growing up, he picked up an interest in hunting quail and pheasant, as well as fishing. With that upbringing, he still enjoys nature and being outdoors as much as possible.

He chose dentistry as a career based on his talents in science and the pleasure of meeting many interesting individuals while helping them lead a healthier life. The practice of General Dentistry has allowed Dr. Poltera to gain expertise in a wide variety of treatment modalities and to retain an interest in all of it. He has taken advanced training in orthodontics, including Invisalign, as well as oral conscious sedation.

Dr. Poltera is a member of the American Dental Association, Kansas Dental Association, American Orthodontic Society, and DOCS (Dental Organization Conscious Sedation).
