Xillium PH is a homegrown Clinical Support Outsourcing (CSO) company hailing from the City of Love in the Philippines – Iloilo City. Founded in 2011, its two pioneers, Vanessa Belleza and Don Wickelgren, an Ilongga, and an American respectively, have challenged the landscape of healthcare services in both the US and our country. 

They believed that virtual assistance could extend beyond business-to-business setups and into the medical field. The company started its humble beginnings with a 5-person structure and has now grown to a full-scale organization with several office sites and expanding every year. 

Winning within is a big part of our company and we try to embody this in our work practice toward our employees. We encourage the perfect balance between work and life because we believe that winning doesn’t always mean being on top – it may also mean that personal growth is just as important as your career growth. 

We try to develop an open working environment that promises learning on the job and motivating you to strive for the best version of yourself. As you begin your winning journey with us, our employees are always ready to give you a helping hand.
