He continued his education at the University of Cincinnati-Mayfield Clinic & Spine Institute where he completed a Complex Spine Orthopedic & Neurosurgery Fellowship, learning the most up to date skills for the treatment of adult and pediatric spinal pathology.

    In 2008, Dr. Cramer joined the Haider Spine Center. He also volunteers with the Children's Spine Foundation, allowing him to actively help underprivileged children who suffer from spinal ailments. He gained vast experience in evaluating and treating pediatric spinal issues while working at Cincinnati Children's Hospital in Ohio.

    In addition to his clinical experience, Dr. Cramer's fellowship research project was selected for the international American Association of Neurological Surgeons/Congress of Neurological Surgeons Mayfield Clinic Science Award of 2008, presented in Orlando, FL. He became the first osteopathic surgeon to receive the award.
