Attorney bio
Jamie Polito Johnston is a principal at Lasher. Her practice focuses on complex marital dissolutions and legal separations, committed intimate relationships, cohabitation/prenuptial agreements, as well as spousal maintenance, child support, and parenting issues.
Resolution-oriented and providing responsive and personal service to her clients at demanding and stressful times, Jamie represents high net worth individuals with respect to complex and unique financial issues, including the valuation and division of closely-held companies, stock options and awards, family trusts and partnerships, and separate property tracing. Her clients include busy professionals, business owners, entrepreneurs, athletes, executives, and their partners who wish to resolve matters efficiently and with minimal impact on their children and family relationships.
In her 20 years of practice, Jamie has developed a reputation as a compassionate and skilled advocate and advisor for her clients. Whether utilizing traditional dispute resolution methods through litigation, or alternatives such as mediation, or the Collaborative Law process, Jamie helps her clients by developing sound and creative solutions tied to their individual goals and needs, which are often achieved by teaming with other professional experts and advisors, such as CPAs, forensic accountants, parenting experts/coaches and corporate/estate planning attorneys.
