Phone counseling is convenient, focused, and works. However, it is not the right choice for certain circumstances or conditions such as severe depression with suicidal ideation, alcohol and drug addiction, mental disorders such as bipolar disorders, schizophrenia, etc. These are best treated face to face.
These are just some of the areas I address with clients. Please feel free to ask about others not listed:
Family issues
Marriage - solo counseling or both spouses
Parenting
Marriage preparation
Anxiety
