Melody took her time with me and was very knowledgeable and kind. It was my first time seeking any treatment like this. I was nervous. She made it fun for me. This group is terrific and I'll go back.

So, after being a nurse for 35 years and a Front Desk Medical Receptionist for 5... I am extremely particular and know when I have found the best there is!!! Dr.Keller is so so great, along with Molly and Whitney..and Dominique was precious, and so professional!!! If I could give you 10 stars I would, but it is only a 5 star review in this survey as being the top number. Thank you for everything, and especially for giving me sight at 20/40 in my right eye after cataract surgery. You all are THE BEST!!!!!!
