Testimonials
Collated independently by Legal 500 research team.
- Our main point of contact for more than a decade has been Hristo Nihrizov, who is like a part of the team now. His main areas of specialization are telecom and banking, but he is also very experienced in competition matters in the telecom sector. Hristo is an extraordinarily dedicated and reliable lawyer whose advice has been crucial for us on hundreds of occasions over the years. His mastery of the regulatory landscape is matched by a deep commercial understanding of how telecom markets function in practice. Beyond technical excellence, Hristo is an outstanding collaborator — responsive, engaged, and genuinely committed to achieving the best outcome for his clients. Moreover, he has managed to build an exceptional team with matching qualities.
