Dr Baker is AMAZING! I saw her today for an ultrasound guided Cortizone injection. I was quite apprehensive since I had never had this procedure done before. She explained everything in depth before we began and patiently answered my questions. While doing the procedure she told me step-by-step what she was doing before she did it. It was a quick and seamless procedure. I would highly recommend this doctor. She is very thorough and empathetic.
Very professional and explained the process.
Dr. Backer is kind and knowledgeable, she is straightforward in a fun and easy to understand way, which is great for my teenager. She always asks for her honest feedback on how she’s feeling and really makes her feel empowered in her own care.
Straightforward analysis of the situation, yet patiently answered all my questions. Warm personality, but efficient.
