I would recommend Dr Kram to anyone needing help with sleep disorder. He was very knowledgeable and I learned a lot about my condition and felt empowered to take better control of the issue. He spent time to really dive into my sleep study results, presented me with treatment options and finally helped me decide the best solution. In happy to report I've been sleeping better thanks to the CPAP machine I chose and have reduce my sleep apnea attacks from 29/hr to 2/Hr. Above all this he's a great guy, very friendly and listens to his patients and I never felt rushed. Thank you Dr Kram
