    Dr. Halligan came highly recommended from our pediatrician! I was so impressed at his humbling bedside manner, care, concern, and thorough examination of my daughter. He has her best interest in mind and calmed my fears as a parent. Excellent doctor!!

    This physician needs training in late effects. Though he may do well with primary treatment, follow up care is lacking.
