  • Joseph M. Troy

    I endorse this lawyer. In family law, understanding what a particular judge's tendencies are for child placement and financial issues is critical to success. Tajara knows the judges well and has earned their respect as a prepared, experienced and trustworthy attorney. She will vigorously fight for her clients to achieve what is possible, and is strong enough to help clients avoid wasting time, emotion and money on unrealistic or counter-productive ideas.

  • Dawn C. Leemon

    Certain qualities are vital when you are looking for a family law attorney: intelligence, aggressiveness, dedication to clients, and a thorough knowledge and understanding of the law. Attorney Dommershausen has all of these qualities. I have referred friends and family members to her and would do so again without hesitation or reservation. She is, put simply, one of the best.
