Description of Practice

I have a decade of experience helping people through difficult situations, including getting through the challenges of divorce, single parenting, coping with conflicts, and learning how to create better outcomes that serve everyone involved. My mediation services are non-adversarial, equitable, and peaceful. Let mediation be the first way that you both take a step toward life improvement. Do not allow litigation to drain your resources, financially, physically, and emotionally, when you can interact with a mediation process that is designed to help you in a fair, equitable, and cost effective way. As a mediator, I will help you and your divorcing partner to sort out the details of dividing assets, dealing with bills, negotiate spousal support if necessary, calculate child support, develop a workable parenting plan, or mediate post-decree parenting plans when your family needs change. I will write a Memorandum of Understanding that you will add to your court packet when you file your case with the court. You may also give the Memorandum to an attorney for review, if you so desire.

Professional Background

I have an MA in Psychology majoring in Human Development, an MS in Mental Health Counseling, and I am a Licensed Clinical Professional Counselor. I run my own full-time private practice and spent several years as an adjunct professor of psychology. Prior to that, I worked for many years in banking and financial aid and student accounts for a university. In earlier years, I worked in the school districts in Special Education serving children with learning disabilities. I have experienced divorce myself and raised my own children as a 24/7 sole custody single parent for almost 20 years now. I am proud to know the hard work it takes to earn a living and raise children. I would be privileged to help you reach your goals, negotiate a parenting plan that works for everyone, and preserve your resources so that you can enjoy your life.


I have experience negotiating disputes between couples, parents and children, children and their peers, and, quite honestly, people who are rigidly stuck within their own thoughts and attitudes. I think the qualities that have made me a good therapist translate extremely well into the mediation field because I am good at getting to the heart of the matter and using divergent thought processes to solve problems.

Mediation starts better when you arrive prepared, so I suggest my clients have their financial information ready at the first session. Bringing the financial affidavit paperwork from the court system is very helpful since it must be completed anyway. I have links to these and other resources on my website I give equal time to both clients, and make sure that they are able to express themselves constructively without interference from the other person. I will not allow anyone to become destructive as it is in my policy that such behavior will terminate the mediation session, potentially forcing you to start over elsewhere. In terms of the actual assets and liabilities being divided, I gather all of the information first and ask the parties if they have any thoughts on the matters being discussed. I educate my clients about what "fair and equitable" mean to their case. I provide them with resources so that they can understand, for example, guidelines about child support and spousal support. I am able to provide the parties with fresh insight and strategies to help them arrive at a settlement to their marital estate and parenting plan. I think that divorcing parties can think more clearly and sensibly when they are in an environment where they feel supported and heard, and do not need to spend their energy protecting themselves from verbal sparring. I am pleased to provide a positive and constructive environment in my office.


$250 per session, $300 for the Memorandum of Understanding.
