Psychiatry & Psychotherapy

Most psychiatric care focuses on managing symptoms. Evolution Medicine focuses on understanding why they're there.

Dr. Sonya Lazarevic, Dr. Shuki Cohen, and Helaine Polanco provide psychiatric evaluation, psychotherapy, and functional nutrition — individually or as a coordinated team — with an approach grounded in root-cause investigation, not just symptom management or suppression.

Our Approach

Psychiatric Evaluation — Dr. Lazarevic holds board certification in General Psychiatry and Addiction Psychiatry, with advanced training in integrative, functional, and regenerative medicine. Assessments begin with a 60-minute initial evaluation and may take two to three appointments to complete. Comprehensive functional testing — gut health, inflammation markers, hormones, nutritional status — is incorporated where clinically relevant. The goal is a complete diagnostic picture, not a 15-minute med check.

Medication Optimization — Where medication is appropriate, it is used as one component of a broader multi-pronged treatment plan. Dr. Lazarevic reviews existing regimens, identifies medication interactions or over-prescribing, and calibrates treatment to the specific presentation rather than defaulting to the next medication in line.

Psychotherapy — Dr. Shuki Cohen, PhD specializes in trauma-informed approaches including Eye Movement Desensitization and Reprocessing (EMDR), Cognitive-Behavioral Therapy (CBT), Rational-Emotive Behavioral Therapy (REBT), psychodynamic therapy, Dialectical Behavior Therapy (DBT) skills, and motivational interviewing. Available independently or coordinated with psychiatric care. Dr. Lazarevic also integrates psychotherapy within psychiatric sessions, including Intensive Short-Term Dynamic Psychotherapy (ISTDP), Mindfulness-Based Relapse Prevention (MBRP), and supportive approaches.

Functional Nutrition — Helaine Polanco, MS evaluates gut-brain health, nutritional status, and dietary patterns that affect mood, cognition, and treatment response. Available a la carte, as a standalone nutrition package, or within Momentum Care™ Packages.


Addiction, Dual Diagnosis, and This Practice

A significant portion of Dr. Lazarevic's caseload involves substance use — often alongside depression, anxiety, or trauma. Patients do not need to identify as having an addiction to have substance use addressed as part of their evaluation. Many people use alcohol, cannabis, or other substances to manage symptoms without recognizing the connection. Dr. Lazarevic's board certification in both General Psychiatry and Addiction Psychiatry means both conditions receive clinical attention from the same provider — not separate referrals to separate specialists.


What Makes This Different

Board certification across two disciplines — General Psychiatry and Addiction Psychiatry, with additional training in integrative, functional, and regenerative medicine. Fewer than 5% of psychiatrists hold this combination.

Time and clinical depth — Assessments begin at 60 minutes and are not rushed to conclusion. Complex histories are given the appointment time they require — often two to three sessions before the full picture is clear.

A coordinated clinical team — Dr. Lazarevic, Dr. Cohen, and Helaine Polanco work independently or together, with care integrated across disciplines rather than siloed across providers.
