  • Lockhart Design where able to take our broad ideas and translate them into specific plans which captured our vision. From the initial meeting through to the final version Jenna was always helpful with regards to possible changes, suggestions of different layouts and sizing. The completion of designs was always timely and reflected the changes made from previous versions. Meetings were efficient and focused but always mindful of getting it right for the customer. We would be very happy to utilise their des services again.
