Reviews
My husband and I have gone to Dr Nightengale for years. He is very thorough and compassionate. You can’t go wrong with him as your doctor.
Excellent as always! Dr. Nightengale is very personable and has a way of putting you at ease talking about things we would love to pretend don’t exist! Amazing man, excellent work, wonderful office staff. Sincere “Thank You”!
Dr. Nightingale is a very nice & personable individual.
Very friendly and very promp and they listen to the patient and we are very pleased
The staff was very prompt and professional. Dr. Nightengale reviewed my chart prior to entering the exam room. He spent plenty of time with me and answered my questions. He used hand sanitizer on his hands--I never see doctors do that or wash their hands.
