ARBITRATIONS

Frequently Asked Questions

I bring something to the arbitration table that few neutrals can offer: years of experience as a sitting judge, where I presided over complex, high-stakes litigation across a wide range of subject matters. That background shapes everything — how I manage a hearing, how I weigh evidence, how I analyze legal arguments, and how I write awards. Counsel can expect the same rigor and preparation they would bring to a courtroom, without the delays and procedural overhead of court.

I treat the Preliminary Hearing Conference as one of the most important stages of the entire process. It is where I work with counsel to establish a realistic, efficient procedural framework tailored to the specific needs of the case — discovery parameters, motion practice, briefing schedules, and hearing logistics. Time invested at the front end pays dividends throughout. Counsel should come prepared to have a substantive conversation, not merely exchange pleasantries.

Proportionality. Discovery in arbitration should be calibrated to the complexity and dollar value of the dispute — not imported wholesale from federal court practice. I work with counsel to identify the categories of documents and depositions that are genuinely necessary, and I push back on requests that are more about leverage than legitimate need. The goal is to get the right information in the right amount of time to make the process fair for all parties.

I entertain motions that serve a legitimate purpose: narrowing the issues, addressing threshold legal questions, or protecting a party’s rights. I do not permit motion practice to become a delay tactic or a cost-inflating exercise. Before any substantive motion is filed, I require a concise submission outlining the basis for the motion and its likely impact on the proceedings. I will then determine whether a full briefing is warranted.

Promptly. One of the principal advantages of arbitration over litigation is the ability to obtain a final, binding resolution in a reasonable timeframe — and that advantage evaporates if the arbitrator sits on the award. Counsel and parties should expect a well-reasoned award issued on a timeline that respects the urgency that brought them to arbitration in the first place.

Yes, when requested by the parties or required by the applicable rules. A reasoned award provides counsel and the parties with the analytical basis for my decision, which can be valuable — particularly in matters where the parties have an ongoing relationship or where appellate review is a consideration. I am happy to discuss award format preferences during the preliminary conference. I never forget that arbitration is the parties’ process.

I take that seriously and address it directly. My experience on the bench taught me to recognize dilatory tactics quickly, and I am not reluctant to use the tools available to me — adverse inferences, cost-shifting, sanctions where appropriate — to protect the integrity of the process and the interests of the party that is engaged in good faith. Arbitration is meant to be an efficient alternative to litigation, not a slower version of it.

Yes. I am highly experienced and fully comfortable conducting hearings by secure video conference. I provide and host the platform at no administrative cost to the parties. I have presided over numerous complex, multi-party virtual arbitrations—efficiently, effectively, and without issue.


Whether conducted remotely or in person, each matter receives the identical meticulous preparation, focused attention to detail, and the same expectation of professionalism, preparedness, and civility from all participants.

MEDIATIONS

Frequently Asked Questions

My job as a mediator is not to impose a result — it is to create the conditions under which the parties can reach one themselves. That means listening carefully, earning the trust of everyone in the room, and being willing to have candid conversations when they are needed. I come to every mediation fully prepared and deeply familiar with the facts and legal landscape of the dispute, which allows me to engage substantively rather than simply shuttle numbers back and forth.
I review all submissions thoroughly before the session — not as a formality, but because genuine preparation is what separates a productive mediation from an expensive afternoon. I want to understand not just the legal claims but the underlying interests driving each party: what they need, what they fear, and what a resolution actually looks like to them. I encourage counsel to submit both a formal mediation brief and a confidential statement that speaks candidly to the client’s real priorities.
It happens, and experienced mediators know it. When I sense that the dynamic in the room is being driven by counsel rather than by the parties’ genuine interests, I am not reluctant to request time with the principals directly, or to have a frank private conversation with counsel about what is actually serving their client. My role is to facilitate resolution, and sometimes that requires redirecting the conversation with a degree of candor that the process permits and the parties benefit from. Carefully and deliberately. A mediated resolution is only as durable as the conditions under which it is reached. Agreements forged in the shadow of imbalance, pressure, or unequal access to information rarely endure.

I remain vigilant to disparities in resources, sophistication, and bargaining power, and I structure the process to promote fairness, clarity, and informed decision-making for all participants. This is especially critical in matters where an individual appears opposite an institutional party or where differences in leverage may affect the dynamics of negotiation.
That depends on the specific case, and I am happy to discuss it with counsel. As a general matter, early mediation — before positions harden and litigation costs escalate — offers the greatest opportunity for a creative, cost-effective resolution. That said, some disputes benefit from a period of focused discovery before the parties are ready to negotiate meaningfully. There is no universal answer, but the question is always worth asking sooner rather than later.

There is no universal answer, but the question is always worth asking sooner rather than later.
The session is not the end of the process. In my experience, some of the most productive work happens in the days following a formal mediation session, once the parties have had time to absorb the conversations and recalibrate their positions. I remain available to the parties and counsel after the session to assist with continued discussions, follow-up calls, or additional sessions as needed. Settlement is the goal, and I stay engaged until we get there or the parties decide to stop.
Yes, and the scope of that confidentiality is governed by the applicable rules, any mediation agreement the parties execute, and the law of the relevant jurisdiction. Parties and counsel should review those parameters carefully with their own attorneys. What I can say is that I treat everything communicated to me in the mediation — including confidential caucus discussions — with complete discretion, and I will not disclose what one party has shared with me to the other without explicit permission.
