Mental Health Therapy
Our licensed clinicians provide personalized mental health therapy for anxiety, depression, and trauma. Using evidence-based approaches, we help patients develop coping strategies and improve emotional well-being through individualized treatment plans.

EMDR therapy addresses trauma and PTSD through bilateral stimulation techniques. This evidence-based approach helps reprocess distressing memories, reducing their emotional impact while promoting long-term mental health recovery without requiring detailed trauma discussion.

Medication Management
Board-certified providers offer medication management via telehealth consultations. This service includes comprehensive evaluations, prescription management, and ongoing monitoring to ensure safe, effective treatment for mental health conditions like depression and anxiety disorders.
Couples Therapy
Specialized therapy helps couples rebuild communication and trust. Our clinicians address relationship patterns contributing to disconnection, teaching conflict resolution skills and fostering emotional safety to strengthen partnerships and improve relational satisfaction.

Questions
Do I need therapy if I only want medication management?
Our evidence-based approach requires concurrent therapy for medication patients. Frequency is determined collaboratively between patient, therapist, and medical provider.
How does telehealth medication management work?
Telehealth appointments use secure video conferencing with in-person medical assistants. Providers can prescribe medications, review vitals, and coordinate care remotely while maintaining treatment quality.
What happens if I cancel appointments late?
Late cancellations (less than 24 hours notice) may incur fees up to $40. Insurance typically doesn't cover these fees, which must be resolved before future appointments.
What defines your holistic health approach?
We integrate mind-body-spirit connections through combined treatments including psychotherapy, nutrition, medication, sleep hygiene, and environmental factors to address mental health comprehensively.
Do you accept out-of-network insurance?
We work with out-of-network insurance plans. Patients may face higher copays (e.g., 30% vs 20%) when we're not in-network providers for their insurance carrier.
Are child therapy services available?
Yes, we provide pediatric mental health services. Contact us to discuss your child's specific needs and schedule an appropriate evaluation.
