Nicole L. Thurner is a partner with the firm of Sinatra & Istik Law Office, PLLC. She believes that people reach out to her for help during the most difficult times of their lives, and she's dedicated her practice to solving those problems efficiently and effectively, while treating each client with compassion and understanding. Nicole believes that her job is to remove the emotional component associated with the types of cases she takes. It is important to Nicole that her clients trust her to take care of them, so they can concentrate on caring for themselves and their families through this difficult time.

Nicole's practice focuses on:

1. All matters related to family law, including custody and visitation (including third-party rights such as grandparents' rights), divorce, the preparation of prenuptial and antenuptial agreements, child support and spousal support, protection from abuse matters, termination of parental rights, and adoptions.

2. Juvenile Dependency law, representing parents and other family members involved in Children and Youth Services matters. Nicole's practice involves parent advocacy, child advocacy, and serving as the conflict counsel Solicitor for the Butler County Children and Youth Services Agency. Because of Nicole's wide range of experience in these areas, she is skilled in knowing and understanding the nuances of Juvenile Dependency, and the consequences of failing to have adequate representation from day one.

3. Estate planning, including preparing Last Wills and Testaments, Durable Financial Powers of Attorney, Durable Healthcare Powers of Attorney (Livings Wills), and Revocable and Irrevocable Trusts.

4. Estate Administration, including preparing and filing inheritance tax returns and assisting the estate's executor or administrator in probating and administering the estate.
