    I am thankful to have Dr. Roberts. He is personable, knowledgeable and always tries to help keep our special needs son up to date. He keeps in touch with our son's Neurologist to make sure they are both on the same page with treatment. He listens to any questions that I may have and I also like the staff. They also try to set up an appointment that is easier for me.

    Over the course of several visits, the front desk staff seem bored and like they would rather be someplace else than than checking you in or out. They are not rude, just disengaged and it seems like doing their job feels like a bother to them. If they were more engaged and seemed eager or at least pleased to help, it would make a huge difference.

    I received a vaccination on the spot that I had not anticipated getting. The doctor said it was needed and said that we should go ahead and do it that day. Caught a little off guard but trusting the doctor, I went ahead and said yes. I ended up having some pretty rough side effects for 2 days. Additionally, hindsight after doing some of my own research, I wish the doctor had been a little more relaxed with the suggesting I need it that day. As it could have waited. I wish he had given pros and cons for waiting and letting me give a decision that felt like I was in control of. Additionally, I wish the side effects would have been talked about during the conversation.

    Hire friendlier staff for front office. She was not very friendly. Just sent me back to the lab but did not communicate anything to the lab that I was here by going back there with me to show me where to go and to speak with the lab person to let them know I was here. I sat down in the chair outside of the lab and waited thinking the lab person knew I was there. Finally the lab person saw me and acted very surprised that I was there. She did wait on me and was very nice even though she was about to close. When I came back out front I told the girl at the front desk that the lab person didn't know I was there and she snapped at me and said rudely that "I told her" but that isn't true the lab girl knew nothing. I sat back down and she said nothing else. I feel like she should have said she was sorry about the con fusion with the lab and atleast tried to make small talk for a few minutes as I was the only one in there. Hire people who want to work and work around other people and who are friendly. It helps put people at ease. Going to the doctor can be an anxious experience and the number one priority should be trying to make the customer feel at ease.
