Thomas M. Pendergrass, RN, PhD in Chattanooga: Psychiatric Care with Clinical Nursing Credentials

Thomas M. Pendergrass is a psychiatrist and registered nurse in Chattanooga who combines psychiatric evaluation and medication management with a nursing background that shapes his approach to patient care. His dual credentials (RN and PhD) place him in a subset of Chattanooga psychiatrists trained in both clinical medicine and nursing theory, a distinction that affects how he structures patient interactions and treatment frameworks.

What Pendergrass Actually Offers

Pendergrass provides psychiatric evaluation, diagnosis, and medication management for adults dealing with depression, anxiety, bipolar disorder, schizophrenia, PTSD, and other conditions treated pharmacologically. His nursing training means he approaches each patient with attention to both symptom management and functional daily living. He operates as an individual provider rather than through a large medical system, which affects appointment scheduling, insurance processing, and continuity. His PhD-level training differentiates him from psychiatrists with MD or DO degrees alone; this typically reflects additional research, theoretical, or advanced clinical study beyond the standard residency.

Services and What to Expect on Cost

Psychiatrists in Chattanooga charge between $250 and $400 for initial evaluations, depending on whether they accept insurance, how they bill, and whether an extended intake is needed. Pendergrass's specific fees require verification directly with his office. Follow-up medication management visits typically run $150 to $250 per session in the Chattanooga market, with frequency determined by condition stability and medication adjustments. Most psychiatrists bill insurance; some offer sliding scales for uninsured patients. You should confirm Pendergrass's insurance participation and cash-pay options before scheduling.

How Pendergrass Compares to Other Chattanooga Psychiatrists

Chattanooga's psychiatric provider landscape includes large health systems like Erlanger and CHI Memorial, which employ psychiatrists on staff; independent practitioners like Pendergrass; and Shared Care, a telehealth-first model that many Chattanooga patients access. A psychiatrist within a hospital system offers integrated care (your primary doctor, your therapist, your psychiatrist on the same electronic chart) but longer wait times, sometimes six to eight weeks for first appointments. Pendergrass as an independent allows faster scheduling but requires you to manage care coordination across providers. Telehealth psychiatry avoids commute time and works well for stable medication management; in-person care like Pendergrass provides allows for physical exams and observation that catch things a video call might not.

Choose Pendergrass if you want in-person psychiatric evaluation, a provider with nursing-informed assessment, and ongoing continuity with one clinician. Choose a hospital-system psychiatrist if you need integrated behavioral health (therapy, medical care, psychiatry on one platform) or have complex medical conditions that warrant system-level coordination. Choose telehealth if distance, scheduling inflexibility, or urgent access is your main barrier.

Who Pendergrass Suits and Who It Does Not

Pendergrass works well for adults with mild to moderate mental health conditions who benefit from stable medication management and prefer consistent one-on-one care. His nursing background makes him attentive to medication side effects and functional health outcomes. Adults with complex psychiatric histories, active suicidal ideation, or acute psychosis are better served in an emergency setting or a psychiatrist embedded in a larger system where crisis protocols and hospitalization are available on-site. Patients who need intensive therapy alongside medication management might find a system-based psychiatrist more practical, since scheduling a separate therapist outside a hospital network adds logistical friction.

What the First Appointment Involves

Expect a 60 to 90 minute initial visit. Pendergrass will take a detailed psychiatric history: when symptoms started, how they have changed, what treatments you have tried, family psychiatric history, substance use, medical conditions, and current medications. He will perform a mental status exam (assessing your mood, thought process, memory, and judgment). Bring a list of all medications and supplements, any previous psychiatric records, and insurance information. He will likely not prescribe anything on the first visit unless symptoms are urgent; many psychiatrists prefer one visit of observation before starting medication. You should ask about his approach to specific conditions you have (e.g., whether he typically starts SSRIs for depression or considers other first-line agents) and his philosophy on medication adjustments.

Hours and Logistics

Contact Pendergrass's office directly to confirm hours and appointment availability; psychiatry practices in Chattanooga vary widely, from 8 a.m. to 5 p.m. traditional schedules to practices offering early morning or evening slots. Parking and location depend on his office location; many independent psychiatrists in Chattanooga operate from private offices or shared medical suites in residential or mixed-use areas. Ask whether he is currently accepting new patients, as many Chattanooga psychiatrists have closed their practices to new referrals due to demand.

Pendergrass's combination of psychiatric and nursing credentials makes him a practical choice for Chattanooga patients who want detailed, clinically grounded medication management and benefit from a provider trained to assess both symptom response and day-to-day functioning.
