I agree with Mike about all that he said: my own skepticism when I hear drug-free promises given on the radio, the need for a neuropsychological assessment by someone who will only do the assessment and send you to others for treatments so that you will have a good diagnostic map, the importance of looking at other possible causes when you are not seeing improvements at school and home.
Have you read the National Institute of Mental Health's MTA Study on AD/HD? It was an extended study of the disorder which validated it as a legitimate medical condition and showed that usually a combination of medication by a well-trained in AD/HD psychiatrist, and behavioral intervention in school and at home made the most impact on the child's functioning. You can find info on the study at www.chadd.org.
75% of children with AD/HD (any of the types, including inattentive type) have other co-occuring neurobiological conditions. This is one reason why a good neuropsychological assessment with someone who really understands attentional issues is so important. Sometimes there is more than one stream feeding the river of inattention at school and home. Those other streams can include auditory processing disorder, depression & anxiety, sensory issues, executive functioning disorder (0rganizational &/or working memory challenges), and many others.
One area often overlooked as a potential problem in attentional issues are sleep disorders. By anecdotal evidence, many children with attentional issues also happen to have a variety of sleep disorders. UC Berkeley Graduate Psychology program has been conducting research specifically on the co-occurrence of AD/HD and sleep disorders. I believe Stephen Hinshaw still heads up that department. He also was one of the key researchers in the NIMH MTA Study I mentioned. A good sleep study can either show what's going awry in your child's brain getting the needed cycles of sleep to support learning and memory or rule out a sleep disorder.
E.g., sleep apnea causes symptoms that mimic AD/HD: inattentiveness, careless mistakes, executive functioning issues, listlessness OR hyperactivity. And some children and adults have BOTH.
While there is great promise in neurofeedback for improving brain efficiency (and working memory in particular with AD/HD), the only program that I am aware that has current research evidence is CogMed out of Sweden. Several universities here in the US were going to be doing independent research on this program, Stanford being one.
Good luck in your search for answers. Be sure to look at the evidence, research-based evidence, that supports any program's claims.
www.chaddnorcal.org has a list of speakers meetings and parent support groups for attentional issues around the bay area, including the east bay.
