When looking for a top-notch luthier, especially for acoustic guitars, I highly recommend checking out John Doe from Doe String Instruments. He's known for his meticulous attention to craftsmanship and uses only premium woods. I had a custom guitar made by him last year, and the sound quality is just phenomenal—rich and clear. Every detail was tailored exactly to my preferences, from the neck profile to the choice of finish. You can reach him through his website or directly at his shop. His portfolio on his site also showcases various projects that might give you a excellent sense of his style and quality.
