Claimed Lawyer Profile

Real Estate Sales:

With over twelve years of real estate sales/mortgage experience as a broker, Joe brings a dynamic to real estate transactions that most attorneys can't & that no real estate agent can.
Give Joe a call about any real estate transaction including FSBOs for a free consultation.
Get better results with a real estate attorney on your side.

Unlawful Detainer:

No one wants to go through the eviction process. Often times, mediation between a landlord and tenant can produce a better result. However, where eviction is the correct course of action, you need an attorney dedicated to your results.

Family Law:

Family Law can be challenging at times, but doesn't need to be. Attitude, the ability to stay rational with the facts, & common sense can easily help this often volatile area of the law into a seamless transition of the next phase of your life.

Personal Injury Law:

You were injured & it's not your fault. Now you are entitled to whatever compensation is necessary to put you back in the position you would have been in had you not been injured.


Mediation is not "one size fits all" and Joe works with the parties to develop effective solutions for their unique situation.
Joe will mediate disputes in the areas of: family law, employment disputes, business disputes, disputes with an emphasis on real estate or insurance issues, and interpersonal disputes.
It is important to Joe that he works with parties engaged in a dispute where mediation is appropriate. Therefore he does not charge for initial consultations. During your consultation, Joe will personally speak with the parties so that all sides can make an educated decision as to the most prudent way to proceed.
Joe commonly recommends mediation prior to the more aggressive step of legal action.
Joe has an efficient and productive mediation style, maintains neutrality at all times, & is completely dedicated to facilitating success.

    Mediation Rates: $250.00 per hour for the first two hours and then $350.00 per hour thereafter. A $500.00 deposit is required prior to the mediation session. Cancellation/Postponement Policy: When the mediation has been scheduled and a cancellation/continuance occurs the deposit will be refunded except for time incurred if I can re-reschedule the time with another matter or if notice is given fifteen (15) or more days in advance. Otherwise, if the cancellation or postponement occurs within fifteen (15) days of the mediation date, the parties will be responsible for the deposit. The cancellation policy exists because time reserved and later cancelled generally cannot be replaced. Mediation Financial Assistance Program: Everyone should have access to quality dispute resolution services at an affordable price. Through the Mediation Financial Assistance Program, you may qualify for a reduction of up to $100 per hour in your mediation fees. Ask about the Mediation Financial Assistance Program when you contact us for more information.
