about us



Lawyers in complex, high-profile cases

Provide effective defense through the use of legal methods fighting against influential opponents. A large part of their time is spent in courtrooms, often attended by mass media representatives.

They are daring, even-tempered and fast-moving. They are also always assertive, regardless of the complexity of the case or presence of a foreign element.


Business Defense lawyers

Defend interests of businesses, their investors, owners and representatives from internal and external risks. The majority of them have had experience of working in law enforcement agencies.

They are direct, acting by the principle ‘quickly and to the point’. They have a unique experience of providing support during long searches or other investigative actions.


Litigation attorneys

Provide support and representation at complex litigations, including involving public authorities. Protection of honor, dignity and business reputation, counteracting hostile takeovers, reinstatement are what these intelligent thinkers are capable of and much more.

They provide support to separate trials as well as the ones within the framework of criminal proceedings.


Lawyers of military personnel

Lawyers’ years of experience in criminal proceedings are beneficial for providing legal assistance to service members. Working on appeals from the military is challenging, firstly because of the emotional and psychological sides.

For a long time, our team has co-operated with the Coordination Headquarters for the Treatment of Prisoners of War, Lawyers of the Armed Forces of Ukraine and the hotline of the Ukrainian Bar Association.


Communication experts

Reinforce the defense of the clients in mass media. They make sure to inform the media and the public through creating newsworthy events and providing commentaries.

Their press releases and visual materials (videos, infographics) help cover important circumstances of the proceedings promptly and clearly.
