Psychiatric/Medication Services

Edgewood psychiatric providers are board-certified, licensed physicians and nurse practitioners providing the following behavioral health services:

  • Initial Diagnostic Evaluations
  • Medication Management
  • Individual Psychotherapy Referral

Our psychiatry professionals focus on identifying and encouraging positive coping styles and lifestyle choices while at the same time working to change the choices/coping strategies that may get in the way. They also spend time educating patients on the various aspects of their issues and treatment options.  Initially, patients will review symptoms, personal history, life goals, and treatment goals with their psychiatric provider. From there the psychiatric professional will create a plan for returning visits to monitor progress and respond to any prescribed medications or new treatment modalities.  The psychiatric provider partners with each patient to optimize wellness with the support of our multi-disciplinary team providing a broad spectrum of therapeutic services promoting physical and emotional health and well-being. Edgewood psychiatric staff work out of our South Naperville, North Naperville, and Lisle locations.

His treatment philosophy focuses on a team approach working with therapists, teachers, and other clinicians. “Psychiatrists work best when they are part of a patient centered team, and use medication to complement other modalities.”  Edgewood fosters that philosophy and creates an environment where clinicians and families can collaborate on treatment.

Commonly Asked Patient Questions

Can I use my EAP to see one of the ECS Psychiatrists?

Unfortunately, EAP services do not cover Psychiatric care. Typically, Psychiatry Services are billed through your primary medical carrier, but occasionally the behavioral health provider is still the payer for the doctor’s claims.  Any questions should be directed to the Billing Department for assistance around understanding and verifying your insurance benefits.

Do the psychiatrists prescribe Methadone or Suboxone?

No, but they will work with and prescribe psychotropic medications for clients who have a substance use history or current substance abuse struggles.

How long is an Initial Intake or Follow up Medication Management Appointment with one of Edgewood’s Psychiatrists?

Our Psychiatric Staff generally spends 40-60 minutes with each adult for their intake appointment.  Initial appointments for children under 18 will take 60 minutes and should involve parent or caregivers.

Follow-up Medication Management Appointments are typically scheduled for 20 minutes each.  In some situations, the doctor may recommend a client returns for a 30 minute follow up appointment to allow more time for family interaction and discussion, review labs and reports requested during the initial appointment, or spend sufficient time evaluating a more complex medication change or adjustment.


What should I expect to happen in the Initial or Follow-up appointments?

At the intake appointment, the doctor will facilitate a thorough initial assessment, which will include but is not limited to:

Psychiatric, Medical, Social, Developmental and Family Health History, Substance Use/Abuse, Potential to Harm Self or Others and the client’s Response to the usual vicissitudes of life such as divorces, job loss, death of friends or family, behavior while driving.

The doctor will likely suggest psychotherapy if not already engaged with a therapist or in some instances, suggest a medication to help with the client’s symptoms.  The doctor will not always prescribe medication at the first visit.

Additional labs or tests may also be ordered to rule out other medical conditions that could be contributing to the patient’s complaints or symptoms.

Follow Up appointments are set to allow enough time for adequate observation, communication, assessment, exchange of information and ongoing decision making. During that time, no question, concern or problem is ever too minor or unimportant to be discussed during a follow-up appointment.  You are also welcome to ask for more time to be reserved for your next visit at the next follow-up appointment.

Ways you can prepare for your Initial Appointment with one of our Psychiatrists:

Write down a list of symptoms you have been having to help facilitate a conversation that is direct and informative during the appointment.

Prepare any important medical or mental health records to be shared with the doctor.

Create a list of your medications and reasons taken or plan to bring your medications in the prescription bottles to the appointment.

As a friend or family member to come to their appointment with you if you feel that they can provide a unique perspective and/or help you feel less anxious or more comfortable in the process.

Write down questions about the diagnosis and about any treatments or further assessments available. Our psychiatrists are very open to exploring alternative care and different treatment fields.  Consider sleep studies, light therapy, chiropractic care, a nutritionist, psychological testing, or group therapy.

How often will I need to return for follow-up visits with the psychiatrists?

Depending on the clinical situation, labs or outside tests ordered, the length of time or frequency of visits will vary.  However, most of our Psychiatric staff will request a follow up visit within 2-8 weeks after the initial intake visit and then will decrease the frequency and increase the time between appointments thereafter to every 3-6 months if the medication is effective and the client is stable.

When the agreed upon length of time on medications has passed, and the original complaints are resolved, the medication will be tapered and possibly discontinued to see if medication is no longer needed to keep the symptoms treated.

What should I do in the event that I am having an emergency related to medication one of the psychiatrists is prescribing?

If a rash has developed after starting a new medication, stop taking the medication and contact the office to make a follow-up appointment in the earliest available time slot.  The intake department will assist in fitting you into an emergency opening.  The client should email the doctor at psychiatry@edgewoodclinicalservices.com.

If a patient has trouble breathing, stop the medication immediately and seek medical attention by calling 911 or going to the nearest emergency room. Once the patient has medical attention, he or she should email the doctor.  The patient should contact our Intake Department at 630.428.7890 x 320 to make a follow-up appointment in the earliest available time slot or will assist in fitting you into an emergency opening.

Other side effects or developing symptoms may occur after starting a new medication.  If the situation seems urgent, the client should contact his or her primary care provider or pediatrician or go to the nearest emergency room.  The patient is welcome to contact the doctor or the Clinical Psychiatric Coordinator via email with non-urgent questions.
