Our Philosophy and Mission
Generations Geriatric Mental Health specializes in the diagnosis and treatment of mental health issues common in older individuals.

Our mission is to provide personalized, integrative care in an environment that fosters patient dignity and respect. We recognize that individuals have unique sets of problems, and we are sensitive to the fact that older adults have very specific needs. Certain mental disorders, such as dementia, tend to occur later in life, and seniors are often faced with loss of family, spouse, health, and social supports. Our practice has a diverse, multidisciplinary team comprised of Geriatric Psychiatrists, Psychologists, Neuropsychologists, Nurse Practitioners, Physician’s Assistants, Social Workers, and Nurses, who have years of experience working with the senior population. We treat individuals with memory problems, depression, anxiety, and other emotional illnesses, and assist patients and their families in coping with aging and illness. We do not work as separate entities, but, rather, our philosophy involves a comprehensive, team approach.

Generations is very patient and family focused. Patients are seen in all care settings, including inpatient, outpatient, and nursing homes. The practice is unique, in that it is the only private geriatrically focused practice in the Manchester area.
We look forward to assisting all patients and their families in resolving their illnesses and struggles.

Dr. Vadalia, the founder and President of Generations Geriatric Mental Health, arrived in Manchester in 1994 with a vision – to improve the quality of life of older adults. He attended medical school at Shree M.P. Shah Medical College at Jamnagar, India. He then completed a residency in psychiatry at Mt. Sinai Medical School in 1992, completed a psychiatric residency with elective in geriatric psychiatry at Long Island Jewish Medical Center in 1993, and then completed a Senior Fellowship in Geriatric Psychiatry there, as well, in 1994. He is board certified in Psychiatry by the American Board of Psychiatry and Neurology. Prior to moving to Manchester, he practiced at the Jersey City Medical Center, Brunswick Medical Center, and Hebrew Home for the Aged at Riverdale

In addition to his outpatient practice, Dr. Vadalia serves as the Medical Director of Geriatric Psychiatry at Elliot Hospital, where he helped to grow and expand the Geropsychiatric Unit.   He serves as a supervisor to geriatric clinicians new to the field, including PA students, APRNs, and medical students. He served as a key member of a senior advisory committee focused on the needs of older adults at Elliot Health System that helped create the Elliot Senior Health Center.  This was the first ambulatory care center in New Hampshire to have its focus dedicated to older adults with geriatric medicine and geriatric psychiatry services co-located.   This model has continued for over 10 years with great success.   Dr. Vadalia has applied the same level of advocacy to legislation aimed at improving advanced care directives for people who lack capacity to make decisions.

Dr. Vadalia has been the recipient of many awards for his commitment and dedication to patients and families, as well as to the community. Such awards include the New Hampshire Hospital Association Medical Staff Award for Outstanding Service to the Hospital and Community (2010); Elliot Health System Physician of the Year Award (2012); Elliot Health System William S. Green Award of Excellence (2013), and New Hampshire Top Doctor (2015).  Most recently, he was selected by the American Association for Geriatric Psychiatry as the recipient of their 2017 AAGP Jeanne Jackson-Siegal Clinician of the year Award.  This prestigious award recognizes an AAGP member who has demonstrated a profound commitment to the field of clinical geriatric psychiatry by providing, promoting, and/or ensuring access to quality mental health care for older adults.

Dr. Vadalia's career has been singularly focused on providing the best care possible to help patients receive an improved quality of life.  He strives to achieve this everyday with every patient.
