Dr Threewitt herself is wonderful. Very knowledgeable and easy to talk to. The office staff is awful. No follow up, no calls back, one receptionist gives different information than the next one you speak with. They often rely on sending you to the after hours office, instead of making appointments.

Horrible bedside manner. I don't remember ever meeting a medical professional as apathetic as Dr. Tanya.After three visits, I will not be seeking her services again. Each time was the same.

I was lucky enough to be referred to Dr. Threewitt by a friend and was so pleased at her demeanor and bedside manner that I plan on remain with her for as long as I can. I found her very compassionate, knowledgeable and patient, meaning she gives you the time of day. She listens, is friendly, and gives you possible alternatives. Her staff is very attentive. I have not one complaint, to me Dr. Threewitt is the best doctor I've ever been to.

This is a doctor who does not research and find out what is best for the patient. She gave me a pill that did not go with the other I was taking. Be very very careful. If you get on her bad side by disagreeing, get a new doctor. This one has control issues as well. As for compassion and a good beside manner - forget it.

When I asked for a hormone panel, I am almost 50 she flat out denied and when I disagreed after seeing her for four years, she wrote a certified letter to me dropping me from her practice. Be careful, she is NOT as nice as she appears. If you disagree with her, she WILL bite.

I feel very comfortable with Dr. Threewitt. So much so, that when I left town, and then came back...I made it a point to come back to her, even though the drive was considerably longer! Well worth it!
