We have had an excellent experience partnering with HR PEO Optimum and would highly recommend them to organizations seeking a knowledgeable, responsive, and reliable PEO - particularly those operating in California. From the outset, Optimum’s entire team has been outstanding. Their sales and transition team ensured a smooth onboarding process, and their payroll, HR generalists, and support staff have consistently been friendly, respectful, extremely responsive, and easy to work with. Their level of professionalism and subject-matter expertise inspires confidence and makes day-to-day HR operations significantly more manageable. We are very satisfied with Optimum’s payroll and expense platforms, which are well-suited for a small business. Beyond technology, their depth of resources has been invaluable. Optimum assisted us with drafting a compliant employee handbook, managing leaves of absence, and supporting both hiring and separation processes with clarity and care. As a California-based PEO, Optimum’s knowledge of state-specific employment laws and regulatory requirements is a major advantage. Their guidance has helped us navigate complex compliance issues proactively, reducing risk and allowing our leadership team to focus on running the business. What truly sets Optimum apart is their partnership mindset. They are not just a service provider, but a trusted extension of our organization—thoughtful, responsive, and genuinely invested in our success. For any executive team evaluating PEO options, Optimum delivers exceptional value, expertise, and peace of mind. We are extremely pleased with their services and consider them a wonderful partner.
