Mirna Callejas is a chef. Neil Speigel is a doctor. He is a Specialist in Physical Medicine and Rehabilitation and Fellowship trained in Sports Medicine. Ms. Callejas and Dr. Speigel crossed paths recently at the Mansfield Kaseman Health Clinic. Mirna had been a patient for several years. She was a patient before the Clinic actually opened its doors, turning to CMR for health care when it arranged for medical services in vans at local churches. Dr. Speigel, who has volunteered his entire career, was instrumental in making the Clinic a reality.
