Practice State



Each family is unique. Recognizing the special nature of matrimonial and family law proceedings, Sonja has dedicated her career to serving individuals whose diverse cases frequently involve significant holdings, business valuation, property settlement, support issues, custody and parenting time issues, antenuptial (prenuptial) agreements, and trust and estate planning. Sonja works with each individual to craft a resolution that addresses the unique nature of each case. If further expertise is required, Sonja draws upon the rich knowledge and experience of over 180 attorneys at Lindquist & Vennum. In addition to her law degree, Sonja possesses an LL.M. (Master of Laws) degree in tax and estate planning. Sonja’s Master of Laws degree sets her apart from other family law attorneys as it gives her a keen ability to assist clients with high income, substantial net worth, and complex financial holdings. Recognizing the financial and emotional aspects of every proceeding, Sonja applies her detailed knowledge of tax strategies, business valuation, and cash flow to quickly analyze the case and develop a plan for swift resolution that minimizes conflict. Over the past 23 years, Sonja has advised on numerous dissolution proceedings with asset values ranging from $1 million to over $200 million. Sonja has been granted fellowship in the American Academy of Matrimonial Lawyers, a distinction shared by only a few attorneys in Minnesota. She currently serves on the Board of Managers and also serves as co-chair of the Substantive Law Committee for the Academy. In addition, Sonja is a trained mediator and serves on the panel of qualified Hennepin County Financial Early Neutral Evaluators. Sonja grew upon on a farm in southern Minnesota. She uses the common sense approach instilled in her to help clients maintain dignity and respect during the traumatic dissolution process. Sonja frequently encourages her clients to participate in mediation. She seeks to diminish the effects of divorce on children and families. When reasoned negotiation does not facilitate resolution, Sonja, an experienced litigator, advocates aggressively for her clients.
