Went to Dr Waltman as a new patient and all seemed well, he had great attitude and seemed genuine, oh boy then the referral comes and it's been almost a month have not had any follow up from their office and nothing from the specialist for a sleep study. Thank god I wasn't sick and needed this office. Long story short , my wife and I will not be back and we are still searching for the right Dr. everyone was right there are very few good doctors here in Las Vegas. Steer clear if you want good ole fashioned care
