About Sean

Whether I am working with families in crisis, either by divorce or custody dispute, or working with families building their family through adoption or surrogacy, I work with compassion, diligence, and integrity.   My goal is to provide quality legal service at a reasonable price while advocating for the client or advising the client on difficult legal decisions.   I enjoy working with clients on creative solutions to difficult problems.   I will be direct and forthright in my counsel and will not sugarcoat or puff any issue just "get the client."   You are paying money for great representation, not a "yes man."   Please contact me should your issue involve: divorce, parentage, child custody disputes, juvenile abuse & neglect, juvenile delinquency, adoptions, egg or embryo donation, surrogacy, or guardianships of minors or disabled adults.

      Mr, Mccumber represented our family when we were seeking Permanent Guardianship our of grandchild. Mr. Mccumber is knowledgeable. When we incurred problems with the negligent father, Mr. Mccumber knew exactly what to do. We are so happy with his expertise. We have our grandchild because of Sean. Thank you so very much. YOU ARE THE BEST!

      Excellent Attorney

      Posted by

      Sean McCumber represented me in my nasty divorce and I could not have been happier with his representation. When I would get upset/heated he kept things calm. He always told me exactly how things were and kept emotions out of it. He is a consummate professional. I strongly recommend Sean and this firm.

      I highly recommend Sean

      Posted by

      I highly recommend Sean for any family law services. He is tenacious and fights for his client. He interacted well with our court appointed guardian ad litem and kept me apprised of next steps in the divorce process. Sean maintains a depth of knowledge on clients’ cases and doesn’t rely on the client to refresh his memory. He’s very responsive via phone or email and extremely efficient with time. Sean is straightforward with his counsel. Sean maintains objectivity in difficult situations and focuses on facts, data, and the law.

      I used Sean McCumber at STG to help me obtain custody of my son. He was professional, personal and understanding. This was a very sensative matter for myself and my son, I couldnt imagine having to have done this without his outstanding support and guidance. The customer service was unparalleled, Sean was very responsive answering all our questions messages and emails. Not to mention very patient in answering our millions of questions. I would highly recommend using Sean!! Thanks Sean!!!

      Professional

      Posted by

      I feel very comfortable with Sean as my divorce lawyer. Whenever I have questions or concerns he always gets back within 24 hours. He listens to my concerns and lets me know how we can achieve a reasonably outcome. He is very easy to talk to, and keeps me in line when my emotions take over. I have and will continue to referrer Sean, to my friends and family.

      Smart, sharp, no nonsense, tough, but nice guy.

      Posted by

      Sean was great. He listened to me but didn't hesitate to step in and advise if he thought I was being too emotional. He respected the way in which I wanted to handle the process (quickly and collaboratively) and didn't waste time or rack up the hours for silly reasons, etc. He's also a really great guy. Loves his kids. Loves Disney. And has tattoos! But make no mistake, he has your back, knows the drill and will keep your best interests in mind. So glad I chose Sean.

      Joseph O'Brien, Divorce and separation Attorney on Sep 11, 2019
      Relationship: Fellow lawyer in community

      Although we have disagreed on issues as adversaries on cases, I can always say Mr. McCumber always works hard, is always prepared, and always maintains his professionalism. That’s why I can always say no matter how many times we may disagree or oppose each other on a matter I always respect him as a professional advocate at the end of the day, and an asset to the legal community.

      Rebecca Krawczykowski, Divorce and separation Attorney on Apr 18, 2019
      Relationship: Opposing Counsel on matter

      I endorse Sean for all types of family related legal matters. Sean is the most experienced attorney for adoption and emerging areas in family law that I know. I have had cases against Sean and found him to be a strong advocate for his clients, while also being fair and reasonable. What sets Sean apart from other attorneys is his focus on the best interests of children, which is rarely a priority for other attorneys when cases become contentious. I frequently refer cases to Sean because I trust that he will do an exceptional job.

      Lisa Giese, Divorce and separation Attorney on Apr 16, 2019
      Relationship: Fellow lawyer in community

      Sean is an experienced guardian ad litem, mediator, and litigator.
