About
A real office on Main Street in Kemmerer, Wyoming.
Not a mailbox, not a call center. Tresp Corporate Services is a staffed Wyoming office that forms companies, serves as registered agent, and keeps entities compliant.
Small-company attention, big-company resources
Most registered agent companies are one of two things: a national brand where you are a ticket number, or a one-person shop that may not answer when something urgent arrives. We built Tresp Corporate Services to be neither.
When you call 307.800.1088 during business hours, a person in Kemmerer answers, not a queue, not an offshore call center, not a chatbot. And because our registered address is a real, staffed, renovated office rather than a mail drop, service of process and state correspondence are handled by someone who understands what just arrived and what it means for your deadline.
What that looks like in practice
- A real, staffed Wyoming office, not a mailbox and not a virtual address
- A person answers the phone during business hours
- Nationwide registered agent coverage, with Wyoming and California as our home jurisdictions
- Formation, compliance, mail, and aged entities under one roof, so nothing falls between vendors
- Access to independent attorneys when a matter genuinely needs legal work

Support staff
Our Kemmerer office is staffed during business hours. Service of process, state correspondence, filings, and client questions are handled here by people who sit in the building, not a call center, not a chatbot, not a mail drop.
Attorneys listed above practice through the independent law firms named, not through Tresp Corporate Services, LLC. TCS is not a law firm and does not provide legal advice. Bar numbers are published so you can verify them; they are not a claim that TCS practices law.
Kemmerer, Wyoming, and why it matters
Our office sits on Main Street in Kemmerer, in a 120-year-old building Elizabeth and Brian Tresp fully renovated to roughly 4,000 square feet, directly across from the original J.C. Penney mother store, the first store James Cash Penney ever opened. We are adjacent to Fossil Fuel Coffee Company, and we are glad to be part of daily life in this town rather than an address on a filing.
That is not decoration. Wyoming registered agent service requires a physical presence in the state, and a great many providers meet that requirement with the thinnest possible interpretation of it. Ours is a building with the lights on and people inside.
Our relationship with Tresp, Day & Associates
We are transparent about this because it matters to how you should use us. Tresp Corporate Services, LLC is an independent service provider that maintains a preferred professional relationship with the law firm Tresp, Day & Associates, Inc. They are separate companies.
The practical division: we handle corporate work, forming entities, acting as registered agent, filing annual reports, maintaining corporate records, forwarding mail. Their attorneys handle legal work, asset protection structuring, trusts, estate planning, succession planning. When a client needs both, the handoff is short. When a client only needs corporate services, they only pay for corporate services.
We are not a law firm
Tresp Corporate Services, LLC does not practice law, does not provide legal advice, and does not create an attorney-client relationship with you. Nothing on this website is legal advice. If your situation calls for legal counsel, we will tell you so and can refer you to Tresp, Day & Associates, Inc. or to counsel of your own choosing.
