I had to fill a Human Resources BP role and I had a very tight timeframe. Ian Hardy from Onyx was brilliant at understanding the candidate brief, sourcing great candidates and ensuring there was a smooth process. Ian gave me a great list of candidates from which I was able to shortlist three people. I found the perfect HRBP for the role and she has hit the ground running. I would not hesitate to recommend Onyx; what sets them apart is that they care about the candidates as well as the organisations they work with.

Michelle Theuma is unique !
She has all the attributes you EXPECT from a Recruiter but also goes that extra mile to ensure that both she and Onyx provide an exemplary service. Michelle CARES passionately about what she does and it shows in every aspect of her work and personality.

Michelle listens to what is asked of her by the client, sources relevant and reliable candidates from a wide variety of sources, ensuring that she follows up both with the candidates and with the company. Michelle researches and knows her candidates and clients, aswell as understanding the roles, companies and industries she is recruiting into.

I would not hesitate to recommend Michelle Theuma and Onyx for your recruitment needs.

Graham ClarkeChief Financial Officer, Membership Organisation
I have been working with Michelle at Onyx for over 6 years now. I come back to Onyx again and again for my finance needs at all the levels due to the levels of dedication, knowledge and professional advice that has always been forthcoming. Unlike many other recruiters, Michelle does not send blanket CVs and speaks to every candidate before sending on details. As our relationship has grown over the years, Michelle fully understands the team and the workload and is, therefore, able to screen candidates at a highly proficient level. In addition, on at least one occasion, Michelle is not afraid to go the extra mile to recommend candidates based on her knowledge of the business, if there is anything I have overlooked. I look forward to many more happy years working together.

Valerie HardenFinancial Controller, Exemplas
I have used Ian to recruit senior finance staff over the last ten years and have always had him as the first person to call when I need assistance in this field. He has never wasted my time with inappropriate CVs. He takes time to understand the brief and almost always hits the mark or has been candid enough to say when he is unable to do so – a rare attribute and one I value in an advisor. I have had no hesitation in recommending him to contacts and their feedback has been consistently positive.
