DR. Lach is THE BEST! He listens to what you say, and answers based on that, If you have a thought, he will tell you if he doesn't think it'd make sense to try, and why, or not and why. He's willing to work with you rather than against, and open to trying something different to see how it works for you, rather than choosing a textbook/blanket type choice like "one size fits all
