Client Testimonials

  • Collaborative Divorce Client

    Siri and her team tirelessly helped me to navigate a difficult divorce process. She was discerning and helped me prioritize what to fight for and where to pull back. She helped me get through my ex's reluctance to negotiate in order to prioritize my child's needs, while always advocating for my better interest. Siri calmed me down when I became anxious or overwhelmed and guided me through the collaborative divorce process with expertise and warmth. Thank you!!!!

  • Estate Planning Client

    Attorneys Siri Goldberg and Ethan Goldberg looked after our family when we were estate planning prior to the birth of our child. They were highly knowledgeable, thoughtful, compassionate and thorough; leaving no stone unturned. They researched international law to ensure our end of life plans and our foreign assets would be handled as we intend. We had documents drawn up for before the birth and after. It put my mind at ease working with them knowing that our end of life planning is secure. This practice has always been generous with me. Attorney Siri Goldberg took my call and helped me gratis, when my mother passed at the start of COVID, guiding me in the right direction when I had to handle the closure of an out of-state-estate. Eternally grateful to have such wise legal minds nestled in the heart of Greenfield.

  • Alternative Reproduction Client

    Siri was awesome to work with on our open sperm donor agreement and second parent adoption. Her office was quickly responsive when we had questions and kept us up to date on what the next steps were. We were so pleased to find a lawyer who was so well versed in LGBTQ family planning.

  • Mediation Client

    Coming to the end of a 30 year marriage, I was very nervous about how to begin and work through a divorce process.  Siri really put me and my spouse at ease with her down-to-earth, warm approach. There were a lot of complicated issues with division of assets.  Siri worked with my financial advisor to sort through the details, and my spouse felt that the division was fair and honest as well.  I think the whole process could have been much more contentious and expensive with another attorney.

  • Custody Litigation Client

    Ethan was wonderful to work with, he listened to my worries and helped me feel secure in the decisions I was making. Child custody and visitation is scary and stressful; however Ethan and Siri made all the difference in my ability to get through it, keeping my child safe and secure. Thank you both so much for all you've done for us.

  • Cooperative Divorce Client

    Siri was a very good lawyer for me. My divorce wasn't complex, but it was complicated due to how far apart the parties were from agreement on how to split assets. Siri was helpful in keeping legal fees down, and advocated brilliantly for me. I'm really grateful for her help

  • Mediation Client

    Throughout the mediation process a lot of ugly personal information was disclosed. Siri was unphased and non-judgmental. She made us both feel so comfortable with the situation we had found ourselves in; she put an end to the drama and made us focus on our goals and our children

  • Guardianship Petitioner

    Siri is a great attorney. She, and her assistant worked really hard for us. I would definitely recommend her services to anyone who needs a family law advocate.

  • Custody Litigation Client

    Ethan was very wonderful to work with. He was able to negotiate and treat my case with care.

  • Cooperative Divorce Client

    Siri had been recommended to me by a friend who was getting divorced. I have since recommended her to other friends. Really, I think we are fortunate to have worked with her.

  • Cooperative Divorce Client

    My spouse and I recently used the Center for Cooperative Divorce after researching our legal options. Siri was patient with us and helped us through the divorce by mediating a parenting agreement that has really worked for our family. The staff drafted and filed all of the court forms and even worked directly with our financial advisors to divide our accounts so that all we had to do was sit back and confirm the transactions. They made the process so much less expensive and arduous than we thought it would be. Highly recommend!

  • Cooperative Divorce Client

    Siri’s openness, empathy and extensive legal knowledge made my uncontested divorce actually rather pleasant! Quick to answer questions in a concise and clear way helped my stress level through the divorce. She helped my ex and I feel like we were on the same team working toward the same goal. If there is anything that can balance the stress level during a divorce, take advantage of it! Siri did just that!

  • Cooperative Divorce Client

    During the single most difficult experience of my life, Siri and her team were a constant presence of reason and empathy. We brought to the Center of Cooperative Divorce, a broken marriage with over twenty years of words unspoken, un-cried tears, and stones to be tossed. With a firm and gentle hand, Siri was able to set goals and objectives and pull us to the finish line.

  • Cooperative Divorce Client

    Tensions were so high when we began mediation and we were all living together. Siri recognized this, and right in a session, went to her desk and began working her network of contacts to help us find rentals and make an appointment with a trusted mortgage broker. This is one example of how Siri went above and beyond.  I highly recommend the very personal, dedicated, and holistic approach of the Center for Cooperative Divorce.

  • Litigation Client

    Ethan Goldberg is a stand up attorney and a pleasure to work with.
