History and Culture


Guy and O’Neill is rooted in a family-based culture with passion for providing exceptional customer service, with a vision since the beginning to be a premier contract manufacturer for leading Fortune 500 consumer product companies.



Back in 1975, Pharmanco, Inc. was founded by Mike Guy as a manufacturer of personal care creams and ointments, and since then the facilities have grown to encompass this spirit of innovation and science. Guy & O’Neill invests heavily in its infrastructure to ensure long term sustained growth. Guy & O’Neill’s culture is one of constant improvement and shared successes. Improvements to our process equal improvements to our products, happier customers, and a cycle of employees being rewarded for the work they put in and care they have shown.

Customer Focused

Guy & O’Neill boasts a customer-focused culture. We are dedicated to the highest possible standards of customer service, quality, price and delivery. Everyone at G&O is willing to go above and beyond to exceed the expectations of our customer. The environment is very collaborative with a high degree of personal accountability and ethical behavior.

We invest in our employees — our greatest assets — and everyone genuinely cares about one another and our collective success. G&O is recognized as a Top Workplace in Southeastern Wisconsin and one of the nation’s Best & Brightest companies to work for.

Our Mission and Community

Guy & O’Neill’s commitment to providing meaningful solutions that make life easier extends to our hometown as well. In fact, we believe businesses have a responsibility to support their communities.

G&O actively supports local organizations through donations, sponsorships and participation. Our major charitable event is the annual food drive for The Food Pantry in Port Washington, Wisconsin. 

We also donate to many local and national charities and organizations, including the American Cancer Society.
