Dr. Rivera has taken excellent care of my mom who has severe Alzheimers/dementia. Mom has suffered a number of episodes requiring hospitalization which resulted in her becoming very unbalanced due to the change in surroundings and unauthorized changes in her meds. Dr. Rivera has always been able to nurse her back to emotional stability which is all one can hope for with such an illness. Though we pay him out of pocket, the money is well spent because of the knowledge, skill, and compassion that he brings to his practice.
