Working with Irina and Paul at Xenogenix was a pleasure indeed, they are intelligent, hard working and dedicated. Irina was amazing at everything, kind and sweet in all her interactions and made me feel comfortable asking questions and all. She is amazing and sincere and so is Paul. I appreciate and am grateful that I got to work with them and no doubts will approach them again in near future for any other assistance, can recommend them anytime to anyone & will do so. Thank you Irina and Paul. You are wonderful.
