About Ossanna Consulting Group

Ossanna Consulting is strongly built upon the model of traditional Human Resources consulting and search; however, our business has evolved to include customized, sophisticated solutions for our most complex business partners and senior HR allies.

Our Mission and Values

Ossanna Consulting Group is a Human Resources organization dedicated to supplementing and enhancing the efficiency, productivity and profitability of our clients by providing best in class HR talent at all levels and in all HR functional areas. We can work at our client’s location or virtually, adapting quickly to our client’s environment and corporate culture to build partnerships inside the organization and within the local community.

We consistently provide quality service by listening to our clients, as well as our consultants and candidates, while remaining flexible and focusing on mutual success. We select, hire and support the highest-caliber professionals, committed to a career in Human Resources to represent our clients.

Our business has succeeded for almost three decades largely because of our mission to exceed expectations, while not varying from our core values. Our success has been measured by creating countless strong and long lasting relationships of mutual success.

Our History

Our 100% female-owned and certified company was founded in 1988 by Nikki Teik, a driven and innovative HR professional who recognized the need for customized Human Resources consulting services, where there was a void for such specialized services for HR practitioners.

Ossanna started in the 1980s at a time when there was a gap of business solutions providers, customized to the HR function. With her roots in diversity and technology, Nikki set out to establish the model of contract recruiting and HR project management provided onsite at initial clients such as Apple Computer, Motorola, Quaker Oats, Hewitt Associates and Walgreens. With this industry in its infancy, the model quickly replicated and expanded locally, nationally and globally and is still grounded in the simple core values of integrity, delivery, cost savings and adding value to each and every relationship we have.

Ossanna has grown to be one of the most recognized names and pioneers in the HR consulting business with the most extensive database of HR talent and endless list of satisfied clients worldwide.

Our People

The success of Ossanna consulting group is largely due to our core team. We never vary on our dedication to quality, delivery and integrity.

Beginning as an onsite HR consultant for Apple Computer, until today, Nikki has shown up to service her clients and candidates with the same goals: to be productive, learn, grow, listen, laugh, be passionate, be real, have fun and ALWAYS do the right thing for every single person she comes in contact with.
