Do you often feel sad and struggle to get through the day? Do you have difficulty finding the energy to engage in self care practices? Have you been through trauma or loss which has negatively impacted you? Do you just feel stuck and need support, guidance, and encouragement with navigating how to move forward? I primarily work with adult and adolescent populations in navigating life transitions and stressors which leave us feeling stuck, depressed, and anxious while struggling to function in the ways we desire. I enjoy supporting others in navigating their life journey and finding ways to create positive change.

Physical symptoms (Chronic pain, tension, fatigue, sleep issues etc.
I specialize in treating Trauma (single event, long-term and attachment) with experiential therapies, including EMDR & Somatic Experiencing. These interventions recognize the need to go beyond changing your thoughts and focus on helping people regulate the body sensations and emotions that continue to be experienced. For example: a person may know that a traumatic event is over and yet continue to feel the emotion of anxiety and the body sensation of muscle tension (never truly relaxing or feeling safe). This can activate an impulse to run away from situations, become angry/defensive or shut down (depressed/ avoidant/dissociative)

I'm the Chief Medical Officer at Stella Center. For over fifteen years, my goal has been to help people experiencing mental health challenges find relief. As an anesthesiologist, I discovered the use of stellate ganglion block (SGB) for treating PTSD, eventually perfecting the protocol into the dual sympathetic reset (DSR), an advanced stellate ganglion block (SGB). Symptoms we treat include disrupted sleep, panic attacks, irritability, hypervigilance, difficulties concentrating, depression, sexual dysfunction, and more.

Waitlist for new clients
I specialize in helping individuals cope with the difficult emotions and lifestyle changes that often go along with coping with health problems, chronic illnesses and in particular, heart disease. When facing a new diagnosis, a negative health event (such as stroke or heart attack) or adjusting to a major surgery, it is common for people to experience emotional distress and disruptions to their sleep, appetite and quality of life. Often these are normal reactions that get better after a short while, but at times these stresses can persist and make recovery and health management more difficult than need be.

Sleep or Insomnia Therapists

How effective is treatment for insomnia?

The most effective treatments for insomnia are behavioral techniques that reduce anxiety, including anxiety about falling asleep, and allow the body’s natural cycles to be recalibrated. The most common treatment is cognitive behavioral therapy for insomnia (CBT-I), which researchers have found to be more useful than medication, with rates of success as high as 80 percent.

Are there specific medications for sleep problems?

There are many medications, both over-the-counter and prescription that treat sleep problems. Supplements such as melatonin are popular and may help, though there is little evidence that it is more effective than a placebo. Prescription medications such as zolpidem are sometimes prescribed.

Are there natural treatments for sleep problems?

There are many natural treatments for everyday sleep problems. Reducing blue-light emitting screens, setting a regular bedtime, regular exercise, reducing caffeine and nicotine consumption, and keeping the bedroom dark and cool at night are all lifestyle changes that can help those who struggle with sleep but may not reach the level of an insomnia diagnosis.

What’s the difference between having trouble falling asleep and insomnia?

Life events, stress, and anxiety can lead to sleepless nights for everyone from time to time. To be diagnosed with insomnia, a patient must experience trouble falling asleep, trouble remaining asleep, waking up too early, or non-restorative sleep at least three nights per week for at least one month. Sleep problems affect one-third to one-half of the population, while chronic insomnia affects about 10 to 15 percent of people.
