Call your local county medical association, or go to their website. Ask or search for a gerontologist. At this time of year, if you are not changing any of your 2021 insurance plans [HMO or PPO], you'll want to ask if a new Dr you are interested in takes them. You could also check with local friends to see who they recommend. Another possible source for you is your local Area Agency on Aging, which may come under the county senior services.

Finding a new Dr, and not having a good comraderie with your current one, can be frustrating and tiring. With you health concerns, it is in your best interest to have confidence in your medical team! Please let me know what you decide to do, and if I can help further, okay?
