Our Services
Comprehensive care tailored to your needs.
Psychiatry
Comprehensive psychiatric evaluation and medication management for depression, anxiety disorders, ADHD (non-stimulant treatment), bipolar disorder, panic disorder, OCD, PTSD, binge eating and other mental health conditions.
Family Medicine
Primary and preventive care for adults 18+, including but not limited to health screenings, lab reviews, ongoing management of chronic conditions such as high blood pressure, prediabetes and diabetes, high cholesterol, thyroid conditions, smoking cessation, and weight management.
Family medicine appointments are not yet available — coming soon.
Weight Loss
Your weight loss journey should feel supported, not overwhelming. We offer personalized, medically supervised care, including GLP-1 medications like tirzepatide and semaglutide and other options, tailored to you, your health goals, and lifestyle.
Addiction Treatment
Telehealth treatment for adults with alcohol use, tobacco and other addictions, using non-controlled medications.
We do not prescribe controlled substances, including buprenorphine (Suboxone), benzodiazepines, stimulants, or phentermine. We do not provide detox or withdrawal management.
Whole-person care: your clinician may address more than one concern in a visit when it falls within their specialty. Dr. Dan Nicolau provides treatment for psychiatric conditions, weight loss, and addictions. Family medicine with Lacey Nicolau, FNP-BC is not yet available — coming soon. Depending on complexity, some concerns may need their own appointment, and each appointment is billed separately.
We treat patients 18 years of age and older.
Our practice philosophy: Good care starts with getting to know you as a whole person. Together we'll talk about your work, relationships, and home life, your cultural and educational background, and any medical conditions you're managing. Understanding these pieces helps us make an accurate diagnosis and build a treatment plan that fits you.

Important: Telehealth Visits Only — Tennessee & Virginia Patients
All appointments are conducted by telehealth. To be seen, you must be physically located in Tennessee or Virginia at the time of your visit. If you will be outside these states on the day of your appointment, please let us know at least 24 hours in advance so we can reschedule.

Dr. Dan Nicolau
MD — Psychiatry, Obesity Medicine, Addiction Medicine
Dr. Nicolau is a board-certified psychiatrist practicing medicine since 2010, board-certified in Psychiatry, Obesity Medicine, and Addiction Medicine. He takes a thoughtful, patient-centered approach to mental health and wellness.
A patient is not merely a list of symptoms that make up a condition. All aspects of your life need to be understood. How is your job and home life? What is your ethnic and educational background? Do you have any medical problems? These questions and many more are needed to understand you and provide the right diagnosis and treatment for you. In most cases a combination of medication and talk therapy will give the best results. I am a triple board certified physician that can help you start feeling well again.
