If you manage a Colorado small business or HR team, you probably already know that switching 401(k) providers could improve your plan: but knowing that and actually making the change are two different things.
You may be wondering:
These are reasonable questions. A retirement plan is important, and changing providers should not feel like a leap into the unknown.
The good news is that joining Castle Rock PEP starts with a focused, 15-minute PEP Talk. From there, our team manages the complex work behind the scenes so you can move forward with greater confidence and less administrative strain.
The PEP Talk is a strategy session: not a high-pressure sales presentation. It is a practical conversation about your current plan, your priorities, and whether a Pooled Employer Plan (PEP) makes sense for your business.
A PEP allows unrelated employers to participate in one shared retirement plan while retaining important plan design choices. During the conversation, we typically cover:
The purpose is to make the next steps clear. You should leave knowing what can stay the same, what could be improved, and what Castle Rock PEP will handle for you.

A PEP does not mean every employer receives the same one-size-fits-all plan.
You keep control over key plan design features, including:
For example, if your current match helps you attract and retain employees, we can evaluate how that match fits into the PEP structure rather than asking you to abandon it.
The same is true for vesting and eligibility. Your business may have carefully chosen rules based on hiring patterns, workforce needs, or budget. Our plan design process is built around understanding those decisions and preserving them where appropriate.
The PEP provides shared infrastructure. It does not erase your business’s identity or priorities.
Changing retirement plan providers does require coordination. Employee census data, payroll information, plan documents, contribution records, and investment instructions all need to be handled accurately.
That is exactly why the transition should not rest on the shoulders of one busy HR leader or business owner.
At Castle Rock PEP, that coordination is a team effort. Our implementation team, supported by our virtual assistant Rachel (our “Harmony Hero”), works with you, your current provider, your payroll company, and the PEP team to keep the process organized.
Together, that coordination is designed to cover:
You will still provide information and make decisions about your plan. But you are not expected to become a retirement-plan conversion specialist overnight.
Industry conversions commonly involve a defined transition period and, in many cases, a temporary blackout period during which participants cannot make certain account changes while assets move between providers. The exact timing depends on your existing provider, plan complexity, payroll system, and selected transition date.
The important point is to start early enough for the work to be done carefully. A PEP onboarding checklist from Slavic401k provides an example of the information typically needed during implementation.
Skepticism is healthy: especially when someone promises to reduce costs while improving service.
Castle Rock PEP’s pooled structure is designed to create economies of scale by bringing multiple employers together under one plan. Based on Castle Rock PEP comparisons, participating businesses may see average savings of 42% compared with maintaining a separate 401(k) plan.
The potential savings can come from several areas:
Instead of each employer arranging its own plan-level audit, Castle Rock PEP manages the consolidated PEP audit for the pooled plan. This can reduce both cost and administrative coordination.
The PEP structure may also provide access to institutional-quality investment options, including funds such as Vanguard Target Retirement Funds. These target-date funds are designed to adjust their investment mix over time as an employee approaches a target retirement year.
Savings and investment results depend on your plan, participants, and circumstances. The right question is not “Can someone guarantee a certain result?” It is “Can we clearly compare our current costs, services, and responsibilities with a PEP alternative?”
That comparison should include more than the investment menu. Review administration, fiduciary support, audit requirements, participant education, technology, and the time your internal team spends managing the plan.
Employee communication is one of the most important parts of a successful transition. It is also one of the areas where employers often feel the most pressure.
You may be concerned that employees will ask:
Castle Rock PEP helps you prepare for those conversations. We provide communication tools such as:
The goal is to give employees clear information before, during, and after the transition: not overwhelm them with technical language.
Participant engagement can also improve when employees receive more understandable guidance and ongoing support. Some Castle Rock PEP clients have seen participation increase from 67% to 98% after implementing innovative matching approaches and strengthening employee education.
That is not a guarantee for every employer. It is an example of what can happen when plan design, communication, and personal support work together.
This is the most understandable objection: and often the most expensive one.
Retirement plan changes compete with hiring, payroll, customer needs, budgeting, and day-to-day operations. It is easy to decide that a transition can wait.
But if you are considering a 2026 transition, the clock is ticking. Castle Rock PEP’s September 30 hard deadline is designed to give the team enough time to complete plan design, paperwork, payroll coordination, participant communication, and implementation properly.
Waiting does not make the transition disappear. It may simply push the decision into a later window, prolong higher costs, or delay improvements your employees could already be using.
You do not need to make every decision in one afternoon. You do need to begin the conversation early enough to make thoughtful choices.
Here is the practical version:
Discuss your current plan, your goals, and your concerns. Bring questions about match, vesting, eligibility, costs, audits, investments, and payroll.
Review which features you want to keep and which opportunities you may want to explore. A PEP can be customized to your business.
Our implementation team, with support from Rachel, helps gather documents, coordinate with your current provider, manage payroll integration, and guide the required paperwork.
Use the scripts, slides, education meetings, and support resources provided by Castle Rock PEP. Explain what is changing, what is staying the same, and where employees can get help.
After the transition, employees can access investment education, personalized investment advice, financial planning software, and ongoing resources. Your team receives continued support with administration and compliance oversight.
The first step takes 15 minutes. The complete transition requires coordination: but you do not have to coordinate it alone.
Castle Rock PEP is designed to help employers reduce administrative burden while offering a competitive retirement benefit. With fiduciary protection, professional investment management, compliance oversight, a consolidated PEP audit, institutional-quality investment options, and potential average savings of 42% compared with a separate plan, the structure is built to support both employers and employees.
