Andrea Oswald

Nurse Practitioner

Andrea Oswald

My name is Andrea Oswald and I am an Advanced Nurse Practitioner. I graduated from the University of Iowa in 2003 with my Bachelor’s in Science and Nursing and from Clarkson College in 2010 with a Master’s in Science and Nursing and Family Nurse Practitioner. I am certified by the American Academy of Nurse Practitioners (AANP) and I have experience in cardiology and urgent care.

I have a passion for preventative medicine, health and wellbeing and exercise. Through this, I discovered functional medicine and what it means for optimal health and prevention of chronic disease. I have training in functional medicine through the Institute of Functional Medicine which led me to my own personal journey to optimal health and partnering with my colleagues at PrimeLife.

More recently I have had training in hormone imbalance and hormone replacement therapy and enjoy helping both men and women achieve optimal hormone health. I love teaching about what health can truly mean throughout all aspects of life.

I look forward to partnering with you on your journey to health and to provide care that gets to the root of the problem.

I am an Advanced Registered Nurse Practitioner working along with my experienced colleague Melanie Plain, PA-C, and her team at PrimeLife in and Ames, Iowa, to provide a wide range of science-based health and wellness services.

After providing more than a decade in nursing care to patients of all ages and across all stages of care, I know that patients are not a one-size fits all approach, and I pride myself on providing personalized and compassionate care.

Emily Goldsberry

​I am a licensed nurse practitioner in the state of Iowa, with a Masters Degree in Nursing from Walden University specializing in Adult Gerontology Acute Care. I also am certified through the American Nurses Credentialing Center (ANCC) as an Adult Gerontological Acute Care Nurse Practitioner and maintain active privileges at Mercy Des Moines as a Hospitalist.

I’m ready to join you on your journey to optimal health and well-being with a trusting patient-provider partnership, to form a plan of care combining traditional medicine with a more holistic approach, and focusing on preventing disease while helping you get well, stay well, and feel your very best.

When not caring for patients, I enjoy going to the gym, reading, and just relaxing at home with my husband and four children.

Melanie Spencer

Ms. Spencer has advanced training in Sexual Medicine, Hormone Replacement, Functional and Integrative Medicine. Melanie has completed her Integrative Medicine Fellowship with Dr. Andrew Weil through the Arizona Center of Integrative Medicine and is currently completing her Fellowship with A4M-American Academy of Anti-Aging Medicine. Ms. Spencer has studied Anti-Aging Medicine and Sexual Rejuvenation with A4M, Revive Advanced Training Consultants, SottoPelle, Simpatra and is certified through the American Cosmetic Cellular Medicine Association for administration of the O-shot for women and Priapus-shot for men. After practicing full-time Emergency Medicine and Family Medicine, she became overly aware of the limitations that “conventional” medicine posed. As a response to this, Melanie began studying integrative medicine and mind/body/spirit healing methods, along with herbalism and nutritional supplementation that are known to improve health and balance hormones naturally. PrimeLife encompasses 20+ years of specialty training including integrative and functional medicine, exercise physiology, massage and wellness-based practices that we share with patients s that they can incorporate these healing modalities into their life to support their self-healing. Her philosophy for diagnosing and treating hormone imbalance lies in a comprehensive approach that combines both physical and mental-emotional and relational treatment methods. In addition to utilizing these treatments effectively, she also strives to teach patients that their hormone health and general well-being is dependent on: A well-functioning GI system and hormone axis that is supported through nutritious foods A healthy body that is pain-free, along with a balanced emotional state, and a positive mindset A supportive network of relationships with friends, family, and medical practitioners She is proud to bring her decades of medical knowledge to her own clinic, Prime Life. She is equally honored to be joined by such an exciting and experienced team that she has recruited to work alongside her.
