about Nichols & phipps

Our Team

A great customer experience depends on the people behind the Nichols & Phipps brand name.
We would love to introduce you to some of our team members.

Leadership Team

Frederick S. Petrus CPA, MBA

President and Chief Operations Officer

President and COO, Fred Petrus has knowledge and experience in all business areas. You can feel good about hiring Nichols & Phipps because it is under the leadership of a Master HVAC tech, Master Plumber, Master Electrician, Real Estate professional, and Certified Public Accountant in Virginia.

This wide range of knowledge and experience, plus a passion for doing things the right way, means that Nichols & Phipps has the best leadership possible. Sit down and talk with Fred, and you’ll realize how important great customer service is to him too. One of his biggest pet peeves is when companies use free repair call offers to get in the door with the goal of finding things to sell the customer and to pad the bill to pay for the “free” service call. This will never be the case at Nichols & Phipps. The free repair call tactic does not fit with the company values. Honesty is more than just a buzzword; it is the way we run the company.

If you have any questions or concerns for our management staff, feel free to contact me today at (703)-670-8519. Our team is looking forward to working with you and fixing what needs to be fixed.
