“I had a great experience with Dr. Nadel! His office was really busy the day of my appointment, but he really made a point to sit down with me and listen carefully to all my specific concerns. He explained a few different ways we could address my concerns going forward, and gave me pros and cons for each possible solution. He did a great job of informing me about my healthcare options without making me feel rushed or pushed in any one direction, and I felt empowered when deciding which plan I wanted to go with. He answered all my questions, and I really felt heard! ”
