I found Montgomery Little &

I found Montgomery Little & Soran through a divorce support group during the summer of 2020. It took a while after my separation to pull the trigger on the legal process of divorce, so when I was finally ready in August of 2021, I made the call. Benjamin King was the original attorney I consulted with, and he introduced me to Sibylle. She, Ben, and Julie (a paralegal) walked me through the steps it would take to get divorced stating that it could wrap up in as few as 90 days, or could take up to as many as 18 months. I knew that my divorce wasn’t going to be easy, however, Sibylle and the team made it less painful. Working with my ex husband, who’s attorney’s withdrew from the case was very difficult for everyone involved. Throughout the entire process I was reassured that I was doing everything right, and that my patience would pay off. Having a child involved in the case has been emotional, but with the legal guidance from Sibylle, we made it through a long and grueling 12 months with a positive ruling. I will continue to use Sybille for any family law matters while I reside in Colorado. My overall divorce experience was better for choosing to work with an attorney like Sibylle.

Very Helpful

In going thru a divorce under very emotional circumstances, Ms. Sibylle Clark helped me thru a fairly difficult process resulting in what I feel was a very positive outcome. I feel like we, and her assistant Julie, worked thru the various steps as a team very well and were able to discuss issues frankly and to the point. I had already started the divorce process with my ex-wife, prior to coming back to their firm to help me proceed thru the final negotiations. From my experience in my divorce, I feel very comfortable in being able to recommend Ms. Clark to represent others.


Fantastic Attorney

Sibylle Clark is a fantastic attorney. She represented me in a professional, strategic, calm and well reasoned way. She couples strength with integrity. I highly recommend her legal services.

Stellar attorney

Sibylle is a outstanding professional, down to earth and has the ability to see through the games and diversions of opposing counsel. She does not waste your money by chit chatting and is straight to the point. Even when things look difficult and situations are tense she keeps a clear head and in focus. It was a rough ride but I am so glad she was on the drivers seat. I recommend her wholeheartedly. If you want to hire the best, go with Sibylle
