What people say about us

Jan Foryszewski
Having worked with Capital Consulting/Sigma for over four years, I have always found their service to be absolutely professional and reliable at all times, yet highly personable in doing so. Their perpetual willingness to help, high level of expertise and detail orientated approach has certainly helped differentiate them in a competitive market. Prompt payment, discretion and carefully applied due care and attention to our candidates has naturally led them to be a valued Square One partner for many years already, which personally, I hope remains the case for many more to come.
Jan Foryszewski, Square One
