Criminal Defense Attorney

"Ms. Tierney left no avenue uninvestigated and spared no effort in developing facts and compelling mitigation in a federal criminal case. Her work was appreciated by the client and essential to the client’s excellent sentencing outcome. I look forward to working with her again."


Sexual Assault Victim

 After my assault I was warned about the problems I would encounter in the legal system. However, because I worked with Sally Tierney my experience was one that left me feeling empowered and stronger than ever. Sally helped connect me with the right lawyers who were compassionate and dedicated to fighting for me. The legal process was long and difficult, but Sally was up to the challenge. She empowered me with information and options so I could make informed choices. She was a perfect blend of strength and determination when I needed to be encouraged and empathetic and patient when everything seemed to be too much. I wish everyone who has experienced a sexual assault could have someone like Sally fighting beside them. 


Owner of Viken Investigations

"Sally Tierney has worked closely with me at Viken Investigations for the past two years. During that time, she became someone I relied heavily upon during investigations, victim/witness coordination and support, as well as sensitive situations that required something different that I alone could not provide. Sally is non-confrontational in her approach and always positive, yet assertive and courageous when needed. Her ability, dedication, and relentless determination to fight for those who cannot fight for themselves is uncanny. Her strong work ethic and never-give-up attitude proved to be an asset in every case. I look forward to working with Sally and Clear Path Forward in the future."

Incidentally, I am the owner of Viken Investigations and a retired police officer. I have been involved in law enforcement and/or training since 1996 to present.
