Family Lawyer & Mediator.

Since 2007, Ms. Martinez has dedicated her practice 100% to out of court resolutions for couples and families transitioning through divorce and separation. Her focus is finding solutions to today's legal and family questions, with an eye an achieving the goals for the future. Having practiced in family law since 1998, Ms. Martinez has seen the hardships, destruction, and pain of contested divorces and separations in the court system, and understands from personal and professional expeirence the defficiencies of the family court system. Family matters should be handled first by the families themselves. Only when the family is unable to resolve for themselves, should a judge make decisions for them. Who best knows your children? YOU. Who best knows your financial goals and concerns? YOU. Who should have a voice in your financial and family future? YOU. Ms. Martinez and her professional resources work to empower people to make informed and well-reasoned decisions in their divorce or separation.

We've recently add Wills and Trusts to our services, now providing more complete advanced family solutions. There is no "one-size-fits-all" here. Every life and legacy plan is customized to meet the goals of the unique people we serve, making sure their children, finances, and businesses are taken care of the way they want when they can't to do it, and making sure their wishes are honored upon their passing.

Divorce Options Workshops

Educating the public on out-of-court solutions is a top priority for Ms. Martinez. She is a regular guest lecturer at "Divorce Options", a monthly workshop where participants hear from legal, financial, and marriage & family therapy professionals on the topics of divorce litigation, mediation, collaboration, self help, custody, support, working with a difficult spouse, retirement plans, real estate, short sales, and much much more. 


Ms. Martinez is also dedicated to educating and training professionals in the fields of collaborative divorce, mediation, and cultural complexities in family law.

helpful and fair
Diana Martinez was excellent. She took the time to explain very thoroughly each step through the process of divorce. And she made sure everything was clear and understood by both parties involved. I hope I never have to, but I would recommend her to anyone in a similar situation. A big thanks to Diana and her paralegal staff.

Extremely satisfied
Diana L Martinez was my attorney for my collaborative divorce. I could not speak more highly of her. She always had my best interests in mind while at the same time keeping the process completely "collaborative". She is extremely ethical and was always easy to get a hold of and to talk with. She was very understanding and empathetic, putting me at ease and being proactive regarding my concerns. She really had to go above and beyond as the other attorney who had agreed to work collaborative, but did not have the experience or knowledge, therefore it put a lot of the burden of the work on Diana. She was amazing and I am very grateful that I chose her to help me through the process.

Excellent attorney
Diana was my attorney in our collaborative divorce. While working with her over the past year, I've felt that I was in very competent hands. I appreciate her knowledge, integrity and attention to detail. She truly cares about her clients and works hard to achieve equitable results. Above all, I respect her ethics - a rare virtue in the legal divorce world. I would recommend her without reservation!!!!!

Consummate and compassionate professional
I hold Diana in high esteem. She brings a unique blend of legal knowledge, an incredible eye for detail and amazing sensitivity to her collaborative divorce clients. She is extremely well-prepared for negotiations, interacts with a very calm, level-headed approach, and is one of the most articulate people I've ever met. Diana made my "gray" divorce from a difficult spouse as smooth as possible, given the challenging personality we dealt with. I admire and appreciate her greatly. I urge you to interview her if you want to settle legal differences outside of litigation.

Mediation divorce
My number one goal was to stay out of court and with Diana this became possible even when there were several times it seemed impossible - she kept listening to all my suggestions on how to get the other person involved and willing to mediate. In several ways I am not sure that you would call my case typical mediation - probably far from it. All that matters to me is that I did not have to go to court. Diana is absolutely amazing, she is a lawyer that is honest , compassionate about people. She is more concerned with family staying whole and healthy as possible in a difficult time than at getting even with the other spouse. She truly listens and understands the emotions that go along with divorce. She is upfront and honest about how she perceives the circumstances, even when she knows that this will be the hardest talk to have with her client that she cares about so much. She ultimately leaves the decision up to the client. THANK YOU Diana for all your support and quick responses to all my questions and concerns.

Great Mediator
Used Diana (West Coast Mediation) to mediate my divorce. Had it not been for Diana's services we would have potentialy spent tens of thousands more on our divorce. She offered a pre-divorce class that was extremely helpful and I would suggest anyone who is considering a divorce attend even if they don't end up using West Coast Mediation. Because of the services Diana offered we were able to reach a fair and customized solution to our situation which made our divorce and post divorce much better for the whole family, especially the children.

Diana is an amazing collaborative lawyer. She is honest and sets goals and stays focused with achieving them. She is truely in her line of work because it is her calling and it shows. She facilitated the set up of our "team" and was effective in getting through our toughest points with ease. With this "team" in place I was able to learn the necessary skills needed for us all to be successful. As a result I am still able to communicate with my EX about our children without resentment or animosity. Because of Diana's knowledge and experience I am able to raise my children in the most healthiest of atmospheres post-divorce. THANK YOU DIANA!!!!

The Awesomest Mediator ever
How do I start!!!! Diana is an amazingly kind person, freakishly educated in her art, and an amazing listener. She made me feel comfortable in literally the worst time in my life. Diana educated me...I was schooled! I have learned so much from her. I would hire Diana at any time again to take care of business. I can't thank her enough for helping me and guiding me through my divorce with as little drama as possible. I made it through even though I felt like I would die. Honestly, she held my hand, and I made it. I will forever be grateful to Diana for this.

The Best of the Best
Diana Martinez is a very bright and energetic attorney. She is truly passionate about what she does and believes in solving problems peacefully. She always kept me well informed and helped me resolve child support issues with my ex husband without having to go to court. I have worked with quite a few attorneys in my time and none have been as compassionate, trustworthy or efficient as Diana. If you want someone who believes in getting the job done, Diana is your best choice!

Diana Martinez is an excellent attorney.
Ms. Martinez worked well with us during our contract negotiations with another party. She was always well prepared and kept us apprised of all correspondence and communications. She is detailed oriented and very friendly to deal with. She took a lot of time to explain our options to us and presented us with her opinions and professional evaluations of the situations. She was available to us at a moment’s notice and was very responsive when we left messages.

A Lifesaver!
Diana is a true master of her trade. When I was going through my divorce, I did not want to ruin my children's childhood. My husband and I were somewhat amicable, but needed help getting past a lot of what we disagreed on. Everytime I went to interview a divorce attorney, they seemed like they wanted to go to war, and destroy any bit of civility that remained in our family. I did not want that, because I have seen friends' families devastated when going that route. Diana preserved and nurtured our integrity. My ex-husband and I can be civil with one another, and we don't have to run back to Court and have a judge make decisions on issues that come up. The expense of that alone would be overwhelming. We can communicate and reach solutions, thanks to the help of Diana Martinez. Our children are extremely well-adjusted after the divorce, even scoring honor-roll during the process! This is all due to Mediation and Diana Martinez. I give her the highest recommendation possible.

"I endorse this lawyer. Attorney Martinez is an outstanding attorney with an exceptional repuation. She is a credit to the legal profession. I highly endorse her."
Family Attorney | May 25
Relationship: Worked together on matter
"Ms. Martinez's work as a mediator takes conflict resolution to a different level unlike any I have dealt with in practice or heard from colleagues. Her approach is radically different than the court mandated process for civil dispute resolution addressing the fundamental issues that are the underlying cause of the disputes. Her approach is not how to resolve the case quickly, but how to resolve it finally and completely. Although her emphasis is family law and divorce resolution, her approach to mediation and dispute resolution is across the board for all civil disputes. This is a top quality lawyer/mediator."
Family Attorney | Nov 26
