Kimberly Madigan was named a "Rising Star" in family law by Super Lawyers for years 2012-2014.  In 2014, Ms. Madigan was named as one of the Top 10 Family Law Attorneys Under 40 in Northern California by the National Academy of Family Law Attorneys (NAFLA).

In 2012, the firm hired Melissa N. Smart to work as an associate attorney.  In 2014, she was awarded an honor advocate award at the American Academy of Matrimonial Laywers’ Trial Practicum.  She was awarded the J. Lani Bader Award for Academic Excellence for graduating with a rank of first in her law school class. 

In 2014, the firm hired Adam Neufer to work as an associate attorney.  Mr. Neufer brings five years of family law experience to the firm.  Prior to joining Seeley & Madigan, LLP, Mr. Neufer managed his own solo family law practice in San Francisco.  He also worked as an associate attorney at Triano & Byrne where his practice focused on high-asset and high-conflict divorce and family law matters, business and commercial litigation, and construction defect cases. 

Client Focused

What sets us apart is the level of client service our attorneys and staff members provide.  Telephone calls and emails are almost always returned within 24 hours if not sooner, as we recognize that divorce and custody-related matters are some of the most difficult and stressful experiences our clients will face.  We are sensitive to the costs involved, both financial and emotional, and take a big-picture approach to our clients’ cases.  We help our clients stay focused on their children and work priorities.  Our goal is not just to bring the case to a conclusion but to help transition our clients to a better place, with the assistance of outside consultants if necessary.

We understand that for most mothers and fathers their children are their highest priority.  Children are also the highest priority of our family law courts.  We will work closely with you, and outside therapists if appropriate, spend time getting to know you, and help you achieve a child-centered parenting plan, via negotiation or litigation if necessary.


At the outset of your case, we will assess which dispute-resolution vehicle is the most suitable for your case, including negotiation for out-of-court settlement, mediation, collaborative practice, litigation in public court or with a private judge, given the issues at hand, dynamics between the parties, opposing counsel, size of your marital estate and level of income.  While in some cases, litigation is unavoidable, the policy of the State of California and our family law courts is to promote the settlement of family law cases, as is ours. 

We use a team approach, delegating work when appropriate to associate attorneys or paralegals, which ensures that your case will be handled economically.  And, we will work closely with you, keeping you apprised of the developments in your case and giving you cost-savings options whenever possible.

Trial Ready

We know that the most successful settlements come from intense trial preparation.  Accordingly, for those cases that are contested and headed for trial, we prepare them thoroughly.  H. Yvonne Seeley is an experienced civil litigator and spent several years conducting civil jury trials and appeals before transitioning to family law.  All of our attorneys are trained in trial work practice.

Our attorneys represent clients before public court and private judges.  Private judges are a good option for clients with privacy concerns or who desire a more efficient trial or settlement process.
