I have taken both of my children to him, and he is wonderful. He is thorough, patient, caring, professional and experienced. I had been taking my son (he had chronic ear infections) to another doctor that was a specialist, and well known & respected. He was good, but his receptionist always told me it would be two to three weeks before my son could be seen. Too long a wait. Another professional told me that Dr. Thomason had just started his practice in Santa Fe. I called and had an appointment within two days. If he told me to call when my son had certain signs of another ear infection, he also told his recepionist that she was to make room for him ASAP (that day or the next).
