I have been a patient of Dr. Ambler for the past 15 (?) years. Over that time, he has always listened to me and provided excellent and caring medical care. I have seen Dr. Ambler for the gamut of ``routine medical care'' (e.g., annual exams) to the treatment for a severe allergy and hospitalization for an infected animal bite. I admire his commitment to his patients and his skills as a doctor.
