Customer Service & Training Specialist | Advanced Zendesk User

Delivering exceptional customer experiences isn't just what I do—it's what I genuinely enjoy. With more than 20 years of experience in customer service, sales, training, and team leadership, I have built a career around helping customers feel valued, heard, and supported. My career began in telemarketing, where I quickly progressed into leadership roles, eventually becoming National Telemarketing Manager for a stock market training company. In this role, I managed six telemarketing call centers across South Africa, overseeing performance, training, operations, and customer engagement. I have also worked as a Customer Service Supervisor within the healthcare industry, leading support teams and ensuring high service standards for medical aid members. Over the years, I have gained customer service experience across multiple industries, including training, recruitment, healthcare, marketing, and e-commerce. This diverse background has allowed me to adapt quickly to different products, customers, and business environments. I am highly proficient in CRM and customer support platforms, including Zendesk, Salesforce, Zoho, Infusionsoft, HappyFox, and SnapEngage. In addition to providing customer support, I have managed and administered support systems, trained teams, and developed customer service processes. After taking time away from corporate roles to raise my twin sons, I launched and successfully grew my own magazine, achieving a monthly distribution of 20,000 copies. The publication continues to operate today following its successful sale. Working remotely has allowed me to support businesses across the UK, USA, and Australia, often collaborating with international teams and customers across multiple time zones. This experience has strengthened my communication skills, adaptability, and ability to deliver consistent service in a virtual environment. I take pride in creating positive customer experiences, solving problems efficiently, and building lasting relationships. I am self-motivated, dependable, and committed to delivering excellence in every interaction.
