My mission is to provide natural, safe and effective natural medicine to children and adults. I am dedicated and trained to providing both quality primary care, and holistic medicine. At Beachside Clinic we have uniquely designed programs that are catered for the individual by understanding their environmental, mental and bio-chemical needs. I specialize in thyroid and hormone disorders, perform stool parasite and bacteria testing for leaky gut and IBS, prescribe pharmacuetical medications when necessary including bio-identical hormone replacement therapy, and offer many specialty testing.
