Thank you for your interest in engaging Priebe HP TOX LLC for toxicology consulting services. I want to briefly explain why a non‑refundable retainer is required for non‑governmental agencies and defense counsel.
Why a Retainer Is Necessary
Toxicology matters often involve tight deadlines, evolving evidence, and rapid‑response strategy decisions. To ensure I can begin work immediately — even before all discovery is available — I reserve dedicated time on my calendar as soon as I am retained. This early commitment allows me to:
Review preliminary materials
Identify missing or critical documents
Advise on discovery needs
Flag analytical issues
Assess urgency and timelines
This initial work is essential to building a strong scientific foundation for your case.
Why the Retainer Is Non‑Refundable
When I accept a case, I must decline or delay other work to ensure availability for your matter. The non‑refundable retainer compensates for this reserved time and guarantees that your case receives priority attention.
It also creates a clear, predictable engagement structure:
The retainer secures the engagement
Early review and scheduling are covered
Additional work is billed according to the fee schedule
There are no surprises or delays
What the Retainer Covers
Initial case intake
Early review of available materials
Priority scheduling
Immediate availability for time‑sensitive matters
Subsequent work — such as full case review, written opinions, reports, consulting, or testimony — is billed separately.
In Short
The non‑refundable retainer ensures that your case receives the time, attention, and expertise it requires from the very beginning. It allows me to respond quickly, work efficiently, and provide the high‑quality toxicology support your matter deserves.
If you have any questions about the retainer or the engagement process, I’m happy to discuss them.
