Client Reviews
- "Jason Sposeep came highly recommended by a retired judge. He was the consummate professional and skillfully handled every aspect of this painful process. He was tough when he needed to be, knew when to pull back, and was always available to answer questions and calm me down which was not an easy feat. He was conscious of my financial situation and had a great team to help reduce costs when they could. He was able to get a fair settlement for me and I would recommend him most highly."
- "I could not imagine going through this process without the help of Jason Sposeep. The idea of a collaborative divorce was new to me. His guidance through the process was invaluable helping complete the divorce about as smoothly as can be expected. I always felt as if Jason was available to discuss strategy, options, or even to just hear me vent! lol. Beyond his great credentials, Jason is a good guy that supports his clients, listens to their needs, and gets the job done. I couldn't ask for anything more."
- "Jason Sposeep was referred to me by a friend who holds Jason in high regard, and I retained him to handle my divorce in 2018. From the first consultation, I knew that I had chosen the right attorney, as I felt that Jason genuinely wanted to help. Throughout the divorce process, Jason displayed a high level of professionalism and expertise, and he was extremely responsive to my emails. I am very satisfied with the outcome of my divorce, and I will always be grateful to Jason and his team for their role in making an emotional and stressful situation more bearable. I would recommend Jason Sposeep without hesitation."
- "I am extremely satisfied with the results Jason achieved in my divorce. Despite the spate of challenging financial considerations I presented, in the end we got the fair settlement I wanted. I highly recommend Jason Sposeep and his team."
- "Jason Sposeep is a highly professional and dedicated attorney. I retained him for my collaborative divorce process and can honestly say that without his support and guidance it could have been much more challenging and emotionally stressful on all involved. He helped with navigating through the process and finalizing in very short order. Would highly recommend Jason and the collaborative divorce process."
- "I retained Jason Sposeep to represent me in a collaborative divorce process. He had the right mix of being deliberate and aggressive with being reasonable and pragmatic. His style was perfect to achieve the results I was looking for and being an advocate while at the same time showing respect to my ex-spouse and keeping our family's needs in mind. He was skillful in helping us navigate a difficult process and he gained the respect of the family specialist, the financial specialist and my wife's attorney. Ultimately, we all came to a resolution which is practical and something that was a win-win for all parties involved. Even the judge commended Jason for his great work on my case and I highly recommend working with Jason in the collaborative process."
- "I retained Jason Sposeep post decree in late 2015 to help me through some very malicious and deceitful claims made by my ex-wife (the day before my wedding weekend) that denied me access to my daughter. Jason came in and within days had all of the insane charges vacated, and remained committed to making sure my ex-wife could never do this to me, my new family or my daughter again. Jason came in with the knowledge of someone who has been practicing law for 30 years, yet the spirit and determination of a young lawyer on his first big case. Jason is artistically aggressive, yet poised and cerebral in how he makes his case. My entire family is blessed to have crossed paths with Jason and his team."
- "During my divorce through the collaborative process, Jason Sposeep remained fully responsive and dedicated to finding the best possible resolution with each issue. His expertise, integrity, and attentiveness made an extremely difficult situation manageable."
- "Jason Sposeep is an extremely professional and capable attorney. He was always responsive to my concerns and returned calls and e-mails promptly. He was cognizant of my concerns about costs of litigation and would discourage actions that I might inquire about that would not advance my case but only incur unnecessary fees. He was a very strong advocate and I felt assured that he had my best interests in mind. He was not only concerned about the legal issues involved in divorce litigation but cognizant of the emotional toll on the client and very reassuring throughout the process. I would strongly recommend him for someone in need of a divorce attorney."
- "I was referred to this firm by a friend, and could not be more pleased with the entire experience with them. Specifically, Jason Sposeep and Christina Perez-Tineo were fantastic in handling the details of my divorce. They were professional and personable at every step, and they took the time to help explain the difficult parts that I didn’t understand. The rest of the staff were prompt and courteous as well. Going through the divorce was not something I wanted to experience, but I was extremely happy I had this team to help guide me through the process."
- "Jason Sposeep entered into my divorce case almost 3 years into a long and very difficult process. I felt my prior attorney was not working diligently towards an equitable resolution and opted to replace him with an attorney who came well recommended by a friend of the family. I had relocated out of state so my first meeting with Jason was via a telephone interview. Within the first 5 minutes of our conversation I sensed a level of professionalism that had been sorely lacking and immediately engaged his services. After providing Jason with a fairly detailed case study he immediately began to dig in and developed a strong set of opinions for me to consider that he felt certain would finalize my case promptly and in my very best interest. Mission accomplished as we appeared in court just once and brought an end to this nightmare once and for all. Consummate professional, straight shooter and incredibly detailed would be my way of describing Jason's approach to my case, and I would highly recommend him to any friend or family member that needed his high level of assistance. Today, I am able to sleep well at night and look forward to a future filled with love and happiness due to Jason's fine work."
- "Ours was a collaborative divorce. We had already gone through divorce mediation, and I needed an attorney to handle the prove-up without recreating or revisiting what we had already accomplished with the mediation. I am also an attorney, but do not practice divorce law, and did not wish to represent myself. Jason Sposeep handled my case with efficiency, without undoing what had already been accomplished through mediation, but providing value-added advice. I would recommend highly."
- "Jason Sposeep was recommended to me because of his expertise in collaborative divorce. He proved to be knowledgeable, responsive, and accurate in his analyses of the likely outcomes of the proceedings. He was a pleasure to deal with. He was conscientious of costs and we were able to keep them about in line with initial predictions."
- "Jason Sposeep was very professional in handling my case. He always returned my calls and emails in a very timely manner...day or night. We had a year end deadline to meet in the case and he pushed hard to make that happen. My original goals were met with hard work and creative thinking. I would highly recommend Jason."
- "Jason Sposeep was recommended to me by an independent attorney because of his expertise in collaborative divorce. This referral was accurate. He proved to be knowledgeable, responsive, and accurate in his analyses of the likely outcomes of the proceedings. He was a pleasure to deal with. The costs were also about in line with initial predictions."
- "I hired Jason Sposeep after another lawyer (from a different firm) had completely dropped the ball and created a disaster out of something that could have been a simple case. From the moment I met Jason at our initial consultation I felt at ease and knew that he was going to be able to clean up that mess. Not only did he let me know about everything that was going on, he also made sure that every question I had was answered. He told me that he typically responds to phone messages and emails within 24 hours unless it's an urgent matter but he responded to all of my calls and emails within a couple hours. I really can't say enough good things about Jason. I am so lucky to have found such a compassionate professional to handle my case."
- "I recommend Jason Sposeep to assist with any family law issue. He is experienced, intelligent and always professional. His calm demeanor is also a great asset as family law issues are stressful. Jason will advocate for your rights and will also advise you on how to achieve the best outcome."
- "Mr. Sposeep handled a very complicated, multi-party dispute over my joint parenting agreement post-divorce while I was involved in out of state litigation that tangentially involved my children. He very skillfully and tactfully addressed my in and out of state issues to my ex-husband's attorney in Chicago in the utmost professional and knowledgeable manner that I would expect from an attorney with 30 years of experience. His counsel to me in my unique situation was outstanding, and this, no doubt, kept me out of court with my ex-husband and saved me thousands of dollars. He knew when to be bold and fight, and when to sit tight. I am a busy physician, and Mr. Sposeep was very responsive to my schedule and timely requests. I am thankfully past my ugly situation due to his excellent negotiating skills and mature experience. He can definitely 'fight' with the big dogs!"
- "Jason Sposeep was dedicated, diligent and passionate in representing me in my post divorce matters. He is honest and fair. He conducts himself with integrity. He is trusted and respected by the judges. He has a very good understanding of the technicalities of family law and is adept in applying this in real world court situations."
- "Having worked with Jason Sposeep on a number of cases I find him to be an attorney with a rare combination of knowledge, integrity, compassion, and skill in representing his clients both inside and out of the courtroom. I strongly recommend this excellent attorney for yourself and for your family."
