See what our patients are saying about Tatyana Siminak

My initial psychiatric medicine review was exceptionally thorough, professional and compassionate. As a result of insightful discussion the Practitioner realized that a dosage change on a current medication might assist with an issue I had forgotten to mention. I appreciate the professional dedication and attention given to my concerns.
