Arms Assigned Interventions
Active Comparator: home monitoring
home blood pressure monitor
Device: Home monitoring
Participants will receive a home blood pressure monitor and be taught how to use it. They will have an education session to review treatment goals, medications, diet and exercise. They will be asked to see their primary care provider at least every 3 months and the research nurse at 3, 6 and 12 months.
Experimental: monitor & phone call
home blood pressure monitor + phone calls
Other: monitor & phone call
Participants will receive all of the same interventions of the home monitoring group plus they will receive scheduled telephone follow up by the research nurse

Detailed Description:
Participants will all have home blood pressure monitors, education session on controlling their blood pressure and will be randomized to recieve 6 months of intensive telephonic on a set monitoring schedule or no telephonic follow up. Phone calls will be weekly for 4 weeks, then every 2 weeks for 8 weeks then monthly for 3 months.
