Couldn’t be happier with my experience at Dr. Ralston office


He was very attentive, caring, listened, explained everything including testing required and treatments


Dr. Ralston was great to talk to and very understanding with working to make sure my needs were met and any issues were addressed.


Dr. Ralston was great and really explained everything to me.


I’m 21 weeks and have gained 2 lbs since getting pregnant and this doctor told me not to gain anymore weight until 34 weeks.. I have no control over weight gain since I’m growing a human and it’s normal during this time. She also told me I’ll have to deliver a week early and choose a week day as they are not opened on the weekend. Prescribed a medication that lowers blood pressure which is the exact issue I’m having so I don’t see how it’ll help. Violated HIPPA by addressing a vitamin deficiency I have in front of the whole waiting room full of people. Refused to have my B12 level check when I requested it as I do every visit and am supposed to per my neurologists orders. She didn’t give me any answers for questions I had like if I can take a certain medication.
