Sandra Briggman

Financial Director

Sandra who goes by Sandy Briggman is the Financial Director at Changing Tides Treatment Center on the Outer Banks of North Carolina.  Sandy is a graduate from Marywood University in Scranton, Pennsylvania with a degree in Business Administration and a concentration in Management.  The experience that Sandy brings to Changing Tides is her years of working as a Contracts Manager, Pricing Manager, Human Resources Manager, and a company Financial Manager.  Sandy feels that working at Changing Tides Treatment Center is a perfect job for her because not only does she get to work as their Financial Manager but she also believes in the company’s philosophy that “Change IS Possible!”  In the field of treatment and recovery, Sandy has seen clients come through Changing Tides’ doors and change their lives with the help of the supportive staff.  Changing Tides programs and dedication to each person individually has been part of the key to client’s success.  Sandy has chosen to work in this field because she feels that treatment and recovery is near and dear to her heart due to her own family’s affliction with alcoholism and drug addiction.   It is a family disease and there is hope.  Hope and health for the individual and for the family can be achieved through therapy and counseling.  


In Sandy’s free time she enjoys spending time with her children and her grandchildren.  She is also very talented in Stained Glass and Pottery making and has sold many pieces as well as teaches courses for both arts.  Sandy also enjoys living on the Outer Banks and takes advantage of the island as much as she can with water skiing, boating and swimming.


Aubrey Briggman


Aubrey Briggman is the Administrator and owner of Changing Tides Addiction Treatment Center.  Aubrey graduated with a Bachelor’s Degree in Psychology and Family Relations at East Carolina University in Greenville North Carolina.  She then found herself wondering what she could do with a degree in Psychology and found employment working for an addiction treatment center.  Aubrey quickly found that this was exactly the field that she wanted to be in; she found that helping others was very gratifying for her. She then decided to start her Master’s Degree in Professional Counseling a year later so that she could be a more active and integral part of the individual’s treatment.  She enrolled in the Master’s Program at Grand Canyon University in Arizona. Not only does she feel a calling to work in this field and specialize with those who suffer from addiction but she has also experienced loved ones battling addiction as well as current loved ones who are in recovery. She feels truly blessed to be a part of the solution to this problem.  She absolutely loves the Outer Banks; she is what you would consider a local as she has lived on the scenic island for over 20 years and can’t imagine living anywhere else. The island is full of fun adventures and provides a peaceful, serene place to recovery right along the Atlantic Shore.


In her free time Aubrey enjoys spending time with her family, especially her husband and young son.  She takes advantage of the island in the warmer months and spends as much time as she can outside swimming, sunbathing and gardening.  Aubrey grew up in the motel formerly called the Buccaneer which is owned by her parents and was turned into Changing Tides Addiction Treatment Center by herself and her mother and father.


David Briggman

Operations Director

Dave Briggman is the Operations Director at Changing Tides Treatment Center on the Outer Banks of North Carolina.  Dave has a Bachelor’s of Science degree in Physics from Villanova University. Dave started his career as a scientist and was quickly promoted to a Research and Development Supervisor and finally to an R & D Manager at Harry Diamond Laboratories.  He also worked at Fairchild Weston (Schlumberger / Loral) as a Product Manager, reporting to the General Manager and was responsible for product development and manufacturing, personnel performance, contractor and government relations, and finances.  He also worked at Pocal Industries as the General Manager and Vice President and was responsible for all operations of the company. Dave ended up in the Outer Banks because he decided that he needed a change of climates and had vacationed every year to the Outer Banks since he was only a couple of months old.  He and his wife bought a motel that was originally called the Buccaneer Motel. He owned and operated that motel for approximately 20 years before deciding to be a part of the change needed in the world in the addiction crisis and has been a major part of changing the motel over from the Buccaneer to Changing Tides Addiction Treatment Center.  Dave oversees any function of Changing Tides Company that can affect the quality of performance and client care. Dave also meets occasionally with clients to establish rapport and ensure that they are receiving all they need from the program. Dave feels that the field of addiction recovery is a priority and is very close to home as he has a son in recovery and has witnessed the destruction of families from addiction as he is also a North Carolina Guardian ad Litem volunteer, advocating for abused and neglected children.  Dave believes that Changing Tides’ multi-faceted recovery approach is the most effective philosophy in the field. Dave is certified as all staff members are in Medication Management, Client/Patient Rights, Confidentiality of Substance Use Treatment Information, HIPPA, Substance Use Disorders Part 1 and 2, Structured Group Therapy Approaches, Brief Models of Family Therapy, Best Practices in Substance Use Treatment Engagement, Biopsychosocial Model of Addiction, Blood borne Pathogens, CPR/FA Including the Heimlich Maneuver and Seizure Management, Least Restrictive Alternatives and ACA Codes of Ethics.  Dave has also won awards for the following:

In his free time Dave enjoys spending time with family which is constantly growing.  He also is a lover of sports, especially soccer and football. He enjoys getting together with his peers and playing pickle ball at least 3 times per week and loves taking his boat out on the sound for sunset cruises in the spring, summer and fall months.  

Hailey Knowlton


Hailey grew up in Virginia Beach, Va. She was born in Japan and has had the good fortune to travel and live along the East Coast due to her military upbringing.  Hailey earned her degree in Behavioral Health with a concentration in addictions and a minor in Psychology from Alvernia University. With her educational background, Hailey understands the unique challenges that people with addictions face in today’s society. She feels her involvement in helping others overcome their addiction is very rewarding and takes pride in knowing that she is fostering better life choices for these individuals.

Hailey played field hockey at the collegiate level and ended her hockey career with a conference championship. She enjoys the outdoors and paddle boarding. She is excited to trade in the cold temperatures and snow of Pennsylvania (where Alvernia University is located) to relocate back to the beach in the Outer Banks.

From preceptorship in area Emergency Medicine, to staff nursing in county jails, to Medical Team Administration for tri-county correctional facilities housing both local and federal inmate populations, caring for those in acute withdrawal and managing chronic conditions often associated with the lasting effects of addiction spans throughout Kat’s career.
