Adult Telehealth Psychiatry, Weight Management & Addiction Care in Tennessee and Virginia
Holston Health Associates is a telehealth practice serving adults 18 and older who are physically located in Tennessee or Virginia. Founded by Dr. Dan Nicolau, MD — triple board-certified in Psychiatry, Obesity Medicine, and Addiction Medicine.
Our Services
Comprehensive care tailored to your needs.
Psychiatry
Comprehensive psychiatric evaluation and medication management for depression, anxiety disorders, ADHD, bipolar disorder, panic disorder, OCD, PTSD, binge eating, and other mental health conditions.
Family Medicine
Primary and preventive care for adults 18 and older, including health screenings, lab reviews, and ongoing management of chronic conditions such as high blood pressure, diabetes, prediabetes, 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 disorder, opioid use disorder, tobacco use, and other addictions. We do not provide alcohol 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.
Prescribing policy: Medication treatment is individualized after a clinical evaluation. When clinically appropriate and legally permitted, treatment may include controlled medications. In rare circumstances, a short course of opioid pain medication may be prescribed for acute pain; HHA does not prescribe buprenorphine and does not provide ongoing opioid pain management. Prescribing is at the clinician's discretion and is never guaranteed. In-person evaluation or additional testing may be required. Patients receiving controlled medications must complete a controlled-medication treatment agreement and follow the recommended visit and safety-monitoring plan.

Payment is handled separately from online booking. See Patient Information for details.

Important: Medicare & Medicaid patients
We are unable to see patients who have any Medicare coverage (including Medicare Advantage) or Medicaid (including TennCare and Virginia Medicaid).
We are in the process of credentialing with insurance plans. At this time, appointments remain self-pay. Please contact our office to confirm whether we participate in your specific plan before scheduling. We can provide a superbill — an itemized receipt — that you may submit to your insurance company for potential out-of-network reimbursement.
Cancellations & no-shows
Cancellations with less than 24 hours' notice and missed visits (not joining within 10 minutes) are charged the full visit fee. No charge if a practice-side technology failure prevents the visit.

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. If you join your visit from outside Tennessee or Virginia, we will be unable to see you, and the visit will be treated as a missed appointment and charged the full visit fee.
