Deliverables
From written opinion to the witness stand
The form of the deliverable follows the matter and the applicable standards. Each is grounded in the same disciplined analysis.
Expert reports
Comprehensive written opinions setting out methodology, findings, and conclusions — explicitly bounded to what the evidence supports.
Declarations & affidavits
Focused sworn statements for motions, discovery disputes, and evidentiary hearings.
Rebuttal reports
Direct responses to an opposing expert, identifying where conclusions outrun the underlying artifacts.
Deposition testimony
Clear, defensible testimony — and preparation of counsel on the technical issues at stake.
Hearing testimony
Testimony at evidentiary hearings, including authentication and admissibility questions.
Trial testimony
Explaining complex mobile evidence to a judge or jury without overstating what it proves.
Our Standard
Credible because it is careful
An opinion is only as strong as its limits. We state assumptions, identify the data’s boundaries, and decline to claim more than the evidence supports.
That discipline is what survives cross-examination — and what makes the opinion useful to the court.

Frequently asked questions
How quickly can you deliver an expert report or declaration?
Turnaround depends on the facts and circumstances of the matter — the volume of data, the number of devices, and the questions the opinion must answer. Expedited engagements can be accepted for near-term disclosure and hearing deadlines, capacity permitting. We do not promise a fixed turnaround, because a defensible opinion is bounded by the analysis the record actually requires.
Can the expert testify at deposition and trial?
Yes. Engagements may be structured as consulting, testifying, or neutral, depending on the matter. In a testifying role, the work includes expert reports and declarations, deposition testimony, and trial testimony, together with preparation of counsel on the technical issues. In each case the opinions are bounded to what the evidence supports, and no more.
How do the opinions hold up under Daubert and Rule 702?
Reliability under Daubert and Federal Rule of Evidence 702 is a question of method, not adjectives. The approach is to state the methodology, disclose the assumptions, validate the findings against the record, and bound every opinion to what the data supports. Whether a given opinion is admitted is a legal ruling reserved to the court, and we do not represent otherwise.
Evaluate Phone Evidence Before Deposition
Need an opinion, declaration, or testimony?
Engage early so the analysis — and the opinion — are ready when the deadline arrives.
Submitting a request does not create an attorney-client, expert, or consulting relationship. Do not send privileged or confidential materials until a conflict check is complete and an engagement agreement is in place.
