It is my calling to help encourage people to value their personal stories. This is done by recognizing their strengths and using them for healing, recovery, finding balance, and discovering their worth. Prior to becoming a therapist, I managed a program serving severely mentally ill, homeless adults. I was privileged to support this routinely under-served population here in San Diego, giving me a renewed perspective on the value and worth of every human life.

Working in multiple settings across many different states has deepened my appreciation for the diversity of experiences that make our lives beautiful and that can also leave us wounded.

Listen, here’s the thing. If you’ve come this far, you’ve most likely read a lot of therapist profiles, and may read a lot more. Any therapist is probably going to tell you that they are equipped with what it takes to help you, and for the most part, that’s probably true. But just like any relationship, the therapist/client relationship has to be two things: A good fit, And not an easy fix. The truth is, mental and emotional health and well-being isn’t like a fad diet. You can’t keto your way to stability. Being healthy is a lifestyle, a commitment to working at something that can sometimes seem daunting.

Anxious perfectionism shows up as shame, self-criticism, stress, and chronic guilt & self-punishment. No matter what you do, you're always falling short. It's exhausting, but you don't really know how to relax. You probably don't sleep so well. Maybe you're first-generation, or the sibling who had to keep it all together, or a grown-up "gifted & talented" kid. Anxious perfectionism may also show up as body tension, severe procrastination & indecision, & difficulty with boundaries and people-pleasing. Perfectionism isn't just a cute word for people with high standards: it impacts everything we do in ways we don't consciously realize.

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.
