Providing integrative, evidence-guided care that supports individuals through cancer treatment and recovery, as well as complex chronic health conditions. Offering personalized bio-identical hormone therapy when clinically appropriate to help restore hormonal balance and wellbeing.

About Me

I am both a Naturopathic Doctor and a Medical Doctor (Iran), and I bring that combined clinical lens to integrative cancer care and hormone health. My work is deeply rooted in evidence, research, and a commitment to supporting patients through some of the most challenging phases of their health journey.

Over the years, I have been involved in clinical research and applied medical science, which has shaped how I approach complex and chronic conditions. I use this background to inform care plans that bridge conventional oncology principles and supportive Naturopathic modalities, helping patients optimize their health before, during, and after cancer treatment.

In addition to my adjunctive cancer care work, I also provide care for individuals experiencing hormonal imbalances, and I prescribe bio-identical hormone therapy when clinically appropriate. I find that thoughtful hormone support — individualized to each patient’s history and physiology — can be a key component of comprehensive wellbeing.

An important component of my clinical practice is IV nutrient therapy and vitamin injection therapy, including treatments such as B12 and vitamin D injections, which are used to help support energy production, immune function, and overall physiological recovery where medically appropriate.

My approach is collaborative, evidence-informed, and tailored to each person’s unique clinical picture. I aim to help patients feel supported, informed, and empowered throughout their care.

You may benefit from working with me if you are experiencing:

  • A cancer diagnosis or need support during treatment, recovery, or survivorship

  • Desire for integrative cancer care that complements conventional therapies

  • Hormonal imbalances or menopausal symptoms that may benefit from bio-identical hormone therapy

  • Digestive concerns such as IBS, bloating, reflux, or chronic abdominal discomfort

  • Cardiovascular or metabolic concerns including high blood pressure, cholesterol imbalance, weight changes, or metabolic syndrome

  • Complex or chronic health conditions requiring a research-informed clinical approach

  • Desire for an evidence-guided, integrative, and personalized care plan

  • Desire for IV nutrient therapy or vitamin injection support
