Kate Kostrzewa, Esq is a real coastside gem! Kate is a true gem we are so lucky to have on the Coast. My wife and I utilized her services for our revocable living trust and other estate issues and she was not only down to earth and highly knowledgeable but also very reasonable and easy to work with. A former litigator with a Silicon Valley Law Firm, Kate has the knowledge and experience to draft documents in plain English that will help you and your heirs avoid disputes and costly court battles. We cannot praise her enough and heartily recommend her.

Kate, from KDK Legal, was recommended to us to take care of our family estate planning, not an easy task to address.   Kate made the process as easy as was possible for us, guiding us every step of the way. She is efficient, professional, and very knowledgeable.  It was a bonus to have Kate in town, saving us from a drive over the hill.  We would absolutely recommend Kate to anyone.

I met Kate Kostrzewa through her husband Mark, a fellow musician, and we chatted about our professional lives a bit. It turned out that Kate was an estate planning and probate attorney as well as a fellow Cal Berkeley Golden Bear. When Kate informed me that she was opening her own legal practice, I assured her I would be one of her first clients – for the record, I’m turning 40 next year and thought I should have a will prepared. Kate was outstandingly coherent, thoughtful and accommodating, both to my needs as well as my lack of legal knowledge. She was able to easily and swiftly knock out a somewhat complicated will, and I would not hesitate to return for her services in the future. ‘Painless and professional to the Tee.’

After my husband passed away, I needed help with the title of my property, setting up a will and a trust. Kate was absolutely wonderful. I felt like a weight had been lifted off of me. She is professional, informed and reassuring. She just took care of everything. I would recommend her to anyone in need of these services. Tina

I have known Kate for many years, when she was partaking of my services. When it was time to re-do my Trust Documents, I was reminded that Kate was now providing that service, and I thought, “how perfect!”. I knew she was very intelligent, passionate about any work she took on, detail oriented, determined to complete the goal, and fearless in taking on new challenges, and fun to be with! 

It was a pleasure working with Kate restating my Trust Documents. Her Documents were much more thorough than my last Documents, and included documents that I didn’t even have. She patiently answered all my questions, explained things clearly, was encouraging, and gave useful advice. 

I highly recommend Kate for your estate planning needs.

I have known Kate Kostrzewa for over 30 thirty years and have always found her to be highly intelligent, thoughtful, and detail-oriented.  Kate recently assisted me in creating an estate plan. She answered all of my questions and concerns and helped steer me through this unfamiliar territory.

We are so happy to have stumbled upon KDK Legal when we needed her services (I had fortuitously clipped and saved an article on Kate in the HMB Review). She turned out to be everything one could hope for — and more! Kate is at the top of her game, with all the necessary material at her fingertips. Her package deal offers outstanding value. She guided us through a complicated process with minimum fuss and tears. I would not hesitate to recommend her to everyone.

If you are looking for a trusted advisor or excellent representation, look no further, as Kate Kostrzewa is your advocate. At first, an estate plan appeared to be a daunting task involving very difficult decisions. Thankfully, Kate patiently and methodically guided me along the way. Most importantly, she explained why I needed to do certain things to have the desired outcome and explained what the ramifications would be if I did not. Her ability to keep me calm and focused was extremely helpful. Throughout the whole process, I knew that I was in the right hands and am so happy I decided to seek her services.

I’d been putting off creating a living trust and finally got myself motivated to get it done. I wanted to stay local so I contacted Kate Kostrzewa of KDK Legal for an appointment. Kate made the entire process easy and painless. She gave me direction on what documents I needed to bring with me and asked all of the right questions. I now have a trust in place and feel confident that my family will not have to fight the legal system and the various estate laws once the time comes. Kate is a consummate professional and I’d recommend her in a heartbeat. Ross
