"Lisa Selman-Holman’s online OASIS course is a comprehensive in-depth presentation. It was the perfect preparation course for me to complete, and I’m pleased to report I passed the exam last week! I believer her online course prepares you well for sitting for the COS-C (or the HCS-O) exams."

"So thorough and clear. Loved being able to take the quizzes imbedded in each module. These really helped me hone my skills. The final comprehensive quiz, I took the evening before the real exam. It help me see what my weaknesses were so I could correct them. Scored a 90% on the certification exam! Thank you, Lisa for the best training!"
