    My Doctor is Fabulous. My error was the cause of a late start for the session. She is firm, clear and understanding. I trust her completely and know that she has my wellbeing uppermost in mind. She will pause to explain and make sure that I understand what is happening.

    Dr. Callsen, is inquisitive, gets the complete picture first, always checks the background information, has follow-up questions. Also, Dr. Callsen asks me about not just my health but how I think my health is progressing and if I have any ideas on how to make it better. This is great medical care, the best as I feel involved in my medical plan and treatment and therefore I am more convinced to be very much engaged in the plan towards self improvement.
