Frequently Asked Questions

What is a psychiatrist?

A psychiatrist is a medical doctor who specializes in the field of psychiatry, a branch of medicine aimed to study, diagnose, treat, and prevent mental illness. Becoming a psychiatrist requires a 4 year undergraduate degree followed by 4 years of medical school training and 3-4 years of specialized psychiatric training. Psychiatrists are able to prescribe medications with or without the addition of psychotherapy.

What is a child/adolescent psychiatrist?

A child/adolescent psychiatrist is a psychiatrist who has obtained an additional 2 years of training to work specifically with those under the age of 18. 

What does "Board-Certified" mean and why does it matter?

Board certification signifies the highest level of accreditation within a medical specialty. To become board certified, a physician must complete additional testing and continuing education activities to maintain their certification status. Board certification is not required to practice medicine, but it does illustrate a physician's willingness and ability to apply expert competency in their chosen field of medicine. Dr. Guinan is a board-certified diplomat of adult and child/adolescent psychiatry under the American Board of Neurology and Psychiatry.

How will I know if my insurance will reimburse me for my visit?

If they say no, then your insurance will not offer reimbursement for Seaglass Psychiatry services and you will be solely responsible for payment. If they say yes, you will want to ask about the details of those benefits including what they are willing to cover and if there is an out-of-network deductible that must be met prior to reimbursement.
