Elliana. i put emphasis on an effective communication from the very beginning whereas i make certain that we exchange all important information prior to each appointment so that there are no misunderstandings when we meet in person. if you decide to email me you can expect a quick, straight-to-the-point response (within the first 24 hrs) in which i also answer all your questions, whatever they might be. i am fair and treat everyone with respect.
