Dr. James Stevens earned a Bachelor of Arts in Zoology from UNC-Chapel Hill and a Doctor of Medicine from East Carolina University School of Medicine. He completed a Family Practice Residency at the Fairfax Family Practice Program at the Medical College of Virginia and the first Sports Medicine Fellowship at the University of North Carolina, Chapel Hill in 1991.

He is board certified in both Family Practice and in Sports Medicine. He founded and currently serves as President of Carolina Family Practice & Sports Medicine with locations in Cary, Raleigh, and Holly Springs, NC. He serves as Head Medical Team Physician for the National Hockey League’s 2006 Stanley Cup Champion Carolina Hurricanes, a position he has held since 1997. In addition, he is Head Company Physician for the Carolina Ballet, and he provides sports medicine services to many local high schools. 

His commitment to helping his patients create healthy lifestyles for long-term wellness, along with his desire to provide the highest quality health care services, has motivated Dr. Stevens to establish Essential Health & Wellness (EHW).

EHW offers its patients a comprehensive health care service tailored around their busy schedules with the goal of optimizing their performance and longevity. Dr. Stevens is also a member of, and certified by, the American Academy of Anti-Aging and Regenerative Medicine, the American Academy of Family Practice, and the American Medical Society of Sports Medicine. Dr. Stevens lives in Cary with his wife, Dr. Patience Stevens, and their three sons Eric, James, and Timothy. He is an avid surfer and triathlete.

Dr. Shearer is originally from Martinsville, VA. He attained a bachelor’s degree in Health Sciences from James Madison University and received his medical education from Virginia College of Osteopathic Medicine. He completed an Internal Medicine Residency with University Hospitals Richmond Medical Center in Richmond Heights, OH followed by a Fellowship in Addiction Medicine through Larkin Community Hospital in South Miami, FL. 

Upon completion of his fellowship training, he served as a hospitalist for Mercy Hospital in Ardmore, OK and then as the Medical Director at the Good Shephard Community Clinic in Ardmore, OK. He has completed a fellowship in Metabolic and Nutritional Medicine as well as a Weight Loss Certification through the Metabolic Medical Institute.

He currently holds active board certifications with the American College of Osteopathic Internist, Obesity Medical Association, and American Board of Anti-Aging and Regenerative Medicine.

Born and raised in Asheville, North Carolina, it does not surprise many that Dr. William Haas has established himself as a leader in the fields of integrative and functional medicine. 

Not afraid of breaking the mold, Dr. Haas earned both his medical and business degrees from East Carolina University, one of the nation’s top primary care training programs. He is board-certified in family medicine and attended the University of Arizona for his Integrative Medicine fellowship, where he later served on faculty. In addition to his integrative medicine training, Dr. Haas is a candidate for certification with the Institute for Functional Medicine. 

Currently, Dr. Haas practices integrative medicine and serves as the Chief Medical Officer for Essential Health & Wellness. Additionally, he operates as the Vice President for Clinical  Services at Essential Health Solutions. Prior to his career as a physician, Dr. Haas worked as strength coach and personal-trainer, holding the highest certification with the National Strength and Conditioning Association. 

Previously an avid triathlete, Dr. Haas now enjoys competing in kettlebell sport competitions. Fitness and nutrition remain central to both his personal and professional practice.

Jennie Welner earned her Bachelor of Science in Nursing from Florida State University in 2008. After graduation, she moved to North Carolina and worked in the Neurosurgical/Neurological Unit at Duke University Hospital as a registered nurse, caring for high-complexity patients from 2008 until 2012.

While working full time at Duke, Jennie started her graduate program at UNC Chapel Hill and graduated with a Masters of Science in Nursing in 2012. She then became board certified as a Family Nurse Practitioner (FNP) through the American Nurses Credentialing Center in 2012. In her first year as an NP, she treated patients in a family practice specializing in integrative/holistic medicine in Chapel Hill, NC. 

In February 2012, she attended the American Academy for Anti-Aging Medicine’s Conference. At this conference, she was introduced to and began her passion for bio-identical hormone replacement therapy (BHRT). She developed and implemented BHRT practice protocols for both men and women.

She also has developed experience with weight management, nutritional supplementation, vitamin intravenous therapy, and managing adrenal fatigue. She believes that medicine should not be about treating the individual symptom, but collaborating with the patient to reach their optimum health.

She joined the wonderful team at EHW in 2013 and is thrilled to be able to focus on her passion for BHRT and functional medicine. Jennie is a member of the American Academy for Anti-Aging Medicine, and is certified as a Diplomat by the American Board of Anti-Aging Health Practitioners. She has received additional certification in advanced intravenous nutrient therapy and is currently working on her certification in Weight Management through MMI. 

She lives in Cary with her husband, Mike, their son Gabriel, and daughter, Maya. She enjoys spending time with her family and dog, traveling, and exploring the outdoors. She had the luxury of being within a 30 minute drive from the beach growing up, so now they try to escape to the mountains every chance they get!

Danielle “Dani” Blanchard graduated from Parkland College School of Nursing in 2010. She immediately began working at Memorial Hospital in Springfield, IL on their Transplant, Urology, & Nephrology inpatient unit. After obtaining her coveted “year of experience” she was able to move to North Carolina and work as a Charge Nurse on the Acute Burn & Wound Unit at UNC for two years.

Danielle spent the next few years working in an Outpatient Urology setting, when she decided to make the transition to a more “patient-centered” approach to healthcare. She fell in love with EHW’s values and approach to achieving wellness, rather than simply symptom management.

Danielle lives in Raleigh with her fiancé, Quan, and their daughter, Sydney. In their spare time they enjoy wine tasting, going to the beach, and exploring different restaurants throughout the triangle.

Danielle DeHaven was born in Westfield, NY and graduated from Westfield Academy and Central School, where she was an avid athlete and scholar. She attended Houghton College, and she received her Bachelor of Science in Sports Medicine/Athletic Training with a minor in Education.

In 1998, she and her husband moved to Raleigh, NC, where she began working in orthopedics as a medical assistant. In 2003, she left orthopedics and attended the Medical Arts Massage School in Raleigh and received her massage therapy certification. She opened her own practice, Advanced Therapeutic Massage, with locations in Raleigh and Cary and worked with the Carolina Ballet company as both an athletic trainer and massage therapist. 

Shortly after starting her own practice she desired to return to working with physicians and began a part-time job at Wake Medical Center in Cary, NC as a clinical secretary. Her management skills soon led to a position as the Clinical Secretary Team Leader for the Medical-Surgical unit and eventually to the Team Leader for all of WakeMed Cary Hospital.

Her leadership skills were recognized through receiving the WakeMed Circle of Quality Service Award, a distinguished award throughout the WakeMed Hospital system. In 2009, she was invited to join Dr. James Stevens in AIHF Executive Health as his Clinical Care Coordinator. She continues to work with him today and has expanded her clinical management and leadership skills as the Clinical Operations Manager for Essential Health & Wellness, Cary and Raleigh. 

Danielle is a member of the American Academy of Anti-Aging and Regenerative Medicine. She has been attending these continuing education modules along with Dr. Stevens since October of 2013. In May of 2014, Danielle passed the American Academy of Anti-Aging Health Practitioner certification exam and is now a Diplomat in Metabolic, Nutritional and Functional Medicine. In 2017 she passed the certification exam for the Fellowship in Stem Cell Therapy. Danielle is married to Corey DeHaven and they have two children. When she’s not working, she enjoys playing with her children, quiet time, traveling, and reading a good book (Nichols Sparks being her favorite author).

Sarah Ioveno graduated from New York Institute of Technology with a Bachelor of Science in Life Sciences/Pre-Med in 2006. Throughout college she worked as a medical assistant for a pediatrics office.

Following college, she worked for a chiropractor focusing more on office administration and insurance coding. In 2007, she moved to Cary, NC and began working as the office administrator for a dermatology office.  

Throughout her five years there she expanded her knowledge in office management and insurance coding.  In 2012 she joined Essential Health & Wellness.  She is the office administrator and also helps out with patient care whenever needed. She lives in Cary with her boyfriend Eric and their beagle, Penny.  When she is not working she enjoys spending time with her family, going hiking, and traveling.

Erin Brooks moved to North Carolina with her family in 1997 when her Dad retired from the military. In high school, she developed a love for medicine.  She soon joined her local volunteer EMS squad where she volunteered from 2002-2005.

During her time as a volunteer she earned her Diploma as an Emergency Medical Technician. In 2005, she also earned her Clinical Assistant Certification followed by her Phlebotomy Certification in 2006. After earning her certifications, she worked at Wake Med Hospital in Raleigh, North Carolina as a phlebotomist from 2007 until 2009.

After leaving the hospital she worked for both LabCorp and Quest Diagnostics over the next couple of year before joining Essential Health & Wellness in 2012. She lives in Smithfield with her husband Gerald and their daughter Kenzie. During her time off she enjoys spending time with her family, traveling and reading.

In 2010, she joined Dr. Neal S. Taub a Physiatrist as his medical assistant. She enjoyed her time with Dr. Taub and his patients. After 6 years with Dr. Taub, she moved to Raleigh with her husband, where he is attending school.
