Some Kind Words

Ulster University’s partnership with Harbinson Mulholland has grown from strength to strength over the years, first as patrons of the SME Centre, then through the work of the NI Family Business Forum and subsequent ‘Homegrown’ campaigns.  We are proud of this relationship and have found Darren, Treena and the HM team to be authentic, genuine and passionate about what they do.  They are a joy to work with and experts in their field.
