Prolotherapy & Pain Management

Chronic pain affects millions of Americans of all ages.  Past injuries that linger or are slow to heal, such as injured tendons and ligaments, can be debilitating especially if you're accustomed to an active lifestyle.  Prolotherapy is a regenerative technique which activates your body's innate healing factors in a specifically targeted way in an attempt to restore as much utility as possible.

IV Therapy

IV therapies are known to reduce inflammation, increase daily energy, boost cognitive ability, support the immune system, support adrenal function and replenish nutrient deficiencies.  As such, IV therapy is often used in a tailored way to support our patient's specific needs.  Whether the intention is to support, recover, or otherwise aid in treatment, IV therapy is a valuable tool in the naturopathic doctor's toolbox.

Our Naturopathic Oncology Team

At Aspen Medical Center, we've built a naturopathic oncology team that taps into the power of Naturopathic Specialists, LLC based in Phoenix, AZ.  Two of our board-certified naturopathic oncologists, Dr. Dan Rubin and Dr. Melissa Coats are available for consults and Dr. Rubin joins us in the office each week.  Additionally, Dr. Adam Kozin, our most recent resident, rounds out our cancer care team.
