I couldn’t have found a more competent, capable, conscientious, and caring lawyer than Sandro Monteblanco to help guide me through a very brutal and painful divorce. Suffice to say, he is not only the best attorney I was fortunate to have found in Peru, but I truly believe he’s one of the best in all of South America!

B.C. Del Rey Oaks, California, USA

Dr. Sandro Monteblanco is very committed professional. When our loved one faced criminal proceedings in Peru we always received good, realistic and compassionate advice. As a result of the hard work by the team of lawyers assigned to our case, a prison sentence that would have been 25 years ended up being reduced to less then 7. In a world that was unbeknownst to us, Dr. Monteblanco became our lifeline.

Family G.V.E. Amsterdam, The Netherlands

Attorney Sandro Monteblanco and his legal team are very client-oriented and extremely supportive in our adoption case. Adopting a child in Peru is a daunting, lethargic and complex task to face alone. The Central Authority in our country was supportive but its Peruvian counterpart was not. Attorney Monteblanco was proactively engaged with our case from the beginning and provided us with up-to-date news on the advances made. We are more than happy to have retained the services of such an experienced legal team.
