Medication Management

Medication can play a significant role in improving the symptoms of many psychiatric disorders including mood, anxiety, psychotic, eating, behavioral, and attention deficit disorders. Informing patients of their options and answering questions or concerns about medications is an important part of developing a treatment plan. Not all patient are interested in medications and not all patients benefit. 


Individual psychotherapy can assist patients with many different struggles or symptoms. Whether aiming for symptom improvement, coping with a stressor/transition, or seeking to better understand one's life or relationships, therapy can be a key element to one's well-being.  

Behavior Therapy

Behavioral therapies, such as cognitive behavioral therapy, can be a crucial part of creating change in one's life. Understanding the predisposing, precipitating, and perpetuating components that drive behaviors and learning ways to make changes to disrupt the cycle are often key components of treatment.

Couples and Family Therapy

Dysfunctional or problematic dynamics between a couple or members of a family can lead to unhappiness and struggle. Life circumstances can also strain these relationships over time. Regular therapy can help to repair these bonds.

Scheduling an appointment:  To schedule an initial evaluation appointment, please call 929-243-4843 and leave your name, call back number, and the reason for your call. Dr. Sayer will contact you to perform a brief phone interview in advance of the initial appointment to discuss medical/psychiatric history as well as fees.

Initial evaluations are typically 90 minutes to complete an assessment and to formulate treatment recommendations. Dr. Sayer will provide recommendations for ongoing treatment with him, or referrals to a higher or more specialized level of care.


Duration: Appointments are typically 25-45 minutes in length depending on complexity and type of session. Please make every effort to arrive on time, as each session must end on time out of consideration for the patient with the next appointment.

Cancellations/No-shows: Appointments must be canceled or rescheduled two business days in advance of the scheduled time. Appointments that are not canceled according to this time frame or that are missed will be billed at the usual rate. The 2-day cancellation and no-show policy of many psychiatrists is in place as appointment times are allocated for one patient at a time. While other physician specialties allow for double- or even triple-booking of appointment times (internist, dermatologist), psychiatric appointments times are only booked for one patient.  

Fees and Payment Methods: Cash or check are the preferred methods of payment at this time. Credit/debit cards payment is available as well. Payment is due at the time of service.

Health Insurance: Like many private practice psychiatrists in big cities, Dr. Sayer is an out-of-network provider, meaning that he does not accept payments from insurance companies. If you are interested in seeking reimbursement from your insurance company, contact them directly to obtain information about your “out-of-network behavioral health coverage.”  Dr. Sayer will provide invoices for rendered services. 


Protecting the privacy of patients is of utmost importance.

As in all fields of medicine, confidentiality is protected by the Health Insurance Portability & Accountability Act (HIPAA). A notice of privacy practices will be provided to you at initial evaluation detailing your rights and protections.
