Dr. Lanning seemed very knowledgeable and sure, bringing me a lot of confidence in her for medical care. She shared explanations and details for my care. I don't think I've ever been to a more attentive Dr. I'm very impressed with her and just love her. Thank you for the opportunity to share this about her.

This was my first time to see Dr. Lanning. I couldn't get in to see Dr. Wittenberg and was pleased to hear they had talked before I saw her. My visit was good and I had confidence in her. Thank you.

Amanda and Dr. Lanning are absolutely wonderful. They take such great care of our son. I wouldn't imagine going to another provider.

I love how Dr. Lanning takes time to answer all of my questions and doesn't try to rush and move on to the next patient. I feel very heard by her and that she wants to make sure I feel confident in mine and my child's health.

The receptionist was very friendly and helpful, the doctor, Dr. Lanning was amazing. She sent an adequate amount of time with my daughter who had a lot of questions. She made her feel very safe and comfortable and she educated her a lot. We were very very impressed with her.

This was my first time meeting Dr Lanning. She seemed very nice. I had been with Dr Nancy for 30 years so it's an adjustment.

The problem that I had was simply that the provider was wonderful, been being kind and sweet but she was a lady delivered babies. I was there to try to find out about my diabetes, even though she did take what I believe, nothing was told me that the diabetes, if you tried to send that set up things for me to find out because she must not have had any idea about that area. And so we were just in the wrong place with the wrong person and also she had set me up for without really asking if I could do this to big long things in hell and I can't drive that far and that bar back alone with, you know, right now the problems that weren't at risk by the appointment. It was very sad because.

Dr Lanning was very quick to evaluate and offer several options for treatment. She immediately set up an appt for physical therapy for the very next day. I am very pleased with that treatment today on my very first day!!

Dr. Lanning was very easy to talk to and really listened to all the concerns I had. Would not trust my health care with anyone else.
