Areas We Serve for PEO Services

I had a wonderful experience working with Nancy and team at OptimumHR. They are very prompt in responding to any questions or audit requests. The team was very knowledgeable and helped us stay in compliance with state and federal regulations.

The company I work for switched to Optimum less than a year ago and there has been nothing but up-sides since doing so. Everybody in the company is grateful for the benefits that Optimum provides such as Life Insurance and Dental, something that we've never had before. We are very grateful as well for the extra benefits, such as the Working Advantage discounts on movie theater tickets and theme park admissions. Whenever I have a question regarding payroll or benefits, Fabiola and Shaked have always been quick, patient, and kind in their responses, which is something that I'm very grateful for. All in all, we are very pleased with Optimum and everything they are doing for us.

Been using Optimum for over 10 years at my place of business. Great payroll solution for a small to medium sized business. They take care of payroll, taxes, on-boarding and many other HR needs so you can focus on your business.

Switching to Optimum about a year ago was one of the best decisions our company has made. Their team is incredibly responsive, knowledgeable, and genuinely helpful, making everything from payroll to HR much easier to manage. I highly recommend Optimum to any company looking for a reliable, professional PEO partner. A special thank you to Fabiola and Celeste, they have been exceptional to work with and consistently go above and beyond to provide outstanding support.

I am very pleased with the fast response with the optimum team (specially) with Ana Sakoda on taking care of the questions or events that I have come across. She's very prompt on taking care business.

Optimum HR has been an excellent partner for our company. Their team has provided strong support in payroll, HR, employee benefits, and compliance-related matters. They are responsive, professional, and always willing to help when questions come up. Having a dependable partner like Optimum HR has made a real difference for our business, and we truly value the support they provide. I would highly recommend them to any company looking for reliable HR and payroll services.

Optimum has been our payroll and HR partner for the last 12 years. They have grown and adapted alongside our business as we expanded and transitioned toward a more dispersed workforce. They eliminate the stress of managing payroll across multiple states and staying current with compliance regulations. Their team is very knowledgeable, friendly and happy to help!

I am very satisfied with the level of service we receive from Optimum in providing support for payroll, benefits and HR. My team is Nicole, Julio, Lindsey and Nicki. Thank you Optimum Team!

I've had the privilege of working with Optimum HR to support our mutual client, and I've always been impressed by them. The team is professional, thorough, and very responsive. I'm especially grateful to work with Nicki Tran and Julio because I can always count on their support.

Shaked went on a zoom call with me and was super friendly and knowledgeable to the general information I had. For very specific questions, she provided me the information needed to get.

I always had a great experience working with the OptimumHr team. I would highly recommend this company to anyone!

What a life savor for our small business. We no longer worry about HR, compliance reports, payroll reports and filing of payroll taxes. Employee handbooks too. Optimum takes care of it all. Work comp too. They are a 5 star one stop shop that takes care of all of your payroll and HR needs by leading professionals that know the task at hand. We've been a happy client of just over 5 years.

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.

Nancy and the other team members at Optimum HR has always been helpful and very knowledgable on all my HR and Payroll questions. Easy to to work with and quick response time.

Optimum is the PEO of my company in Los Angeles and my team consists of Nancy, Ana, and Shaked. They are very responsive, efficient and friendly.

I have multiple times reached out to the HR department (Nancy and Ana), and both ladies have responded immediately on the same day or so. They also answer their phone and contact me directly. I cannot do my job without their help. Thank you very much for being so professional.

I have dealt with all of the tech staff at the Optimum store located on High Ridge Road in Stamford, CT. The customer service, attentiveness and kindness of the staff I have spoken to has been superb. They are as follows: Michelle, Alex, Alvaro and Joey. I would not hesitate recommending Optimum to anyone. Thank you. Roni O’Connor

As an employee of a company who utilizes their services, I can vouch this company is a HOT MESS! My taxes were compromised by one of their employees and they are taking no responsibility. I now owe the IRS OVER $17,000 due to their employees mistake. I now have to pay out of pocket for my tax attorney to represent me so I can plead my case. Stay away from this company at all costs. They are a sham!

We use Optimum Employer Solutions as our PEO. They are a great company. I have referred them to multiple partners of ours as well and have had nothing but a great experience. They are very attentive, they care about our company and our employees, and they are super easy to work with. I highly recommend that you use a PEO and you use Optimum for these services.

This company is a powerhouse of people that care about their work and their clients!

Optimum is an amazing company that values its team and clients.
