        from personInfo in Query.All<PersonContactInfo>().Where(pi => pi.Person==person).Take(1).DefaultIfEmpty()
        from customer in Query.All<Customer>().Where(c => c.Curator==person).Take(1).DefaultIfEmpty()
        where customer!=null

     var query =
        from person in Query.All<Person>()
        from personInfo in Query.All<PersonContactInfo>().Where(pi => pi.Person==person).Take(1).DefaultIfEmpty()
        from customer in Query.All<Customer>().Where(c => c.Curator==person).Take(1).DefaultIfEmpty()
        where customer!=null
        select
          new CustomerCuratorListItemDto {
            ID = person.Id,
            Email = personInfo.Email,
            Icq = personInfo.ICQ,
            Name = personInfo.Email,
            Phone = personInfo.Phone,
            Skype = personInfo.Skype
          };
