The whole staff was fantastic. Thank you each and every one of you for your hard work and kindness.

Staff thank you for give us the time needed to discuss my grandson's issue for the visit. Through communication about removing the problem. I was satisfied with our future plan and results.

Our doc - Dr K - was outstanding. I've told everyone about her.

Dr. Krase addressed our Son's Anxiety as well as his physical Health. The Intern working during our visit was kind, inquisitive, a great listener, and thorough. Awesome teamwork Everyone? Thank You__

Finally found a provider who knows what she's talking about. This is the third provider I've taken my daughter to and my search has ended. I'm thrilled.

Dr. Krase was amazing. She was great with my kids and explained to them I. A way that they understood what was going on during the appointment. Her overall attitude was great and you can see how she loves her job. She never seemed bothered by any questions we had and answered them in a way we can all understand. I highly recommend her and we already have appointments scheduled for 6 months!!

Just Thank you.

Great experience with both Dr. Krase, as well as her MA. They were very patient and explained things well. My daughter was anxious about the appointment, but she felt comfortable and was able to overcome her fears as everything was explained to her level of understanding. Thank you!

We absolutely love going to the appointment everyone is amazing!
