I have been a patient of Dr. Cotter for over 25 years, and she is the best! I now travel from Central NH for my appointments. She is very thorough in her examinations. I have very bad astigmatism and Dr. Cotter is very patient and persistent to get the very best contact lenses for my vision. Dr. Cotter has invested in expensive test equipment to document and track eye health. This combined with a great attention to detail makes Dr. Cotter the perfect choice.
