I love Dr. Rettinger but her staff is mostly unfriendly, unhelpful and rude.

Dr. Rettinger (and team) are incredible. They are friendly, helpful and engaging. The only 'problem' is that she is so popular with patients that it can be hard to get in and see her -- she is WONDERFUL! So smart and really works with you to ensure the decisions made will really benefit the patient. We need more doctors like her.

I always have a great experience with Dr. Rettinger. She's very personable & she's very knowledgeable & answers questions clearly but her follow up appointments she's always on point & knows exactly what tests or lab work to go over
