Horizons is directed by Isabel C. Arnold RN, BSN, CCRC a bilingual, certified, and
    highly experienced clinical research coordinator who entered the clinical research
    field in 1993.

    Isabel is from Chile, where she graduated from "La Universidad Catolica de Chile" in
    1990 as a Registered Nurse. For the following six years she worked and gained
    experience in the areas of pediatrics, OBGyn, internal medicine, and cardiology. In
    1993 she also began to participate in clinical research trials, mainly in the areas of
    women's health and internal medicine.

    In 1996 she was hired by Merck, Sharp & Dohme as a clinical research coordinator.
    during the nearly five years that she worked with Merck she attended numerous
    training courses sponsored by the company. She also opened and ran several
    study sites with trials in the areas of cardiology, neurology, bronco-pulmonary and
    women's health.

    In October of 2000 she moved to Denver, Colorado with her fiancé and soon to be husband, Bill Arnold.

    After learning English she continued her career in clinical research at the University of Colorado Cancer Center in
    phase I studies. There she had the opportunity to not only run clinical trials but also to re-organize and manage
    the phase I laboratory. While working at UCHSC she prepared and passed the examination to obtain her RN
    qualification in Colorado.

    After three and a half years working at UCHSC and prior to becoming the director of Horizons she moved to a
    private site as a clinical research coordinator where she ran studies in phases II to IV. She eventually became the
    site manager and under her management the site was recognized by more than 20 pharmaceutical companies,
    Clinical Research and Site Management Organizations in the United States and Europe for the superb quality and
    professionalism of its work. During this period she also obtained her certification as a Clinical Research
    Coordinator through the Association of Clinical Research Professionals.

    Outside of work Isabel and Bill enjoy international travel, landscaping and remodeling their home, hiking in the
    Rockies, and of course a fine glass of Chilean wine in the evening.






    Bill Arnold has been the Business Manager for Horizons since the Center’s inception in early 2007.  Among his
    responsibilities are: the company finances; data management; website design, creation, and maintenance;
    volunteer recruitment; marketing, human resources, and management of the Center’s facilities and information
    technology. In addition to his duties at Horizons Bill was also a member of the Institutional Review Board (IRB) at
    National Jewish Health for two years.

    Bill graduated in 1995 from Southern New Hampshire University at the top of his class with a Bachelor of Arts
    degree in International Business. In 1996 he became the Assistant Director of an international language center in
    Santiago, Chile and was in charge of the Scheduling Department, Study Abroad Department, marketing of the
    Study Abroad Program, and management of over 80 teachers.

    In the fall of 2000 Bill accepted the position of Director of Admissions at the language center’s headquarters in
    Denver, Colorado and moved back to the United States with his fiancée, Isabel. During the following four and a
    half years Bill was responsible for the sales and admissions for the company’s schools in Denver, Colorado;
    Santiago, Chile; Buenos Aires, Argentina; Rio de Janeiro, Brazil and affiliated schools throughout Latin America
    and Spain. He also participated significantly in the international marketing of the language programs, website
    design, and creation of brochures and other marketing materials.

    In the fall of 2004 Bill started his own real estate investment company and within a few months began devoting his
    full attention to his new business. After three successful years in real estate investing Bill now devotes his time and
    energies to his duties at Horizons.

    Outside of work Bill and Isabel enjoy international travel, landscaping and remodeling their home, hiking in the
    Rockies, and of course a fine glass of Chilean wine in the evening.





    Our goal at Horizons is to provide the highest quality study results possible to the sponsors and CROs that we
    work with while ensuring the protection of the rights and safety of the subjects who participate in our studies. The
    fact that we have an excellent reputation for the service we provide is due to the knowledge, skills, and integrity of
    our director, Isabel Arnold RN, BSN, CCRC. We know that the key to providing quality service depends to a large
    extent on the quality of the CRCs that conduct our studies. It is for that reason that Isabel puts so much time and
    effort into personally training the health care professionals we hire who are new to research or in retraining CRCs
    we hire who have previous experience. In addition to training each and every new CRC we employ she then
    continues to mentor them with the goal that we have the best trained research professionals possible. Although
    this method of acquiring high quality professional CRCs is time consuming and requires a great deal of effort on
    the part of Isabel she feels it is worth it if we attain our goal of having a highly trained staff of CRCs who truly care
    about the quality of their work.

    Erika Enriquez-Wickwar, LPN, CRC, Recruitment Manager

    Erika has wide-ranging work experience and has held positions as diverse as: legal assistant, escrow coordinator,
    and model for a promotional events company. The one thing that all of her jobs have had in common though is
    that they all entailed working with people. Erika has always known that working with, and helping people, was what
    she wanted to do. It is probably for that reason that she has always been interested in the health care field and the
    reason she finally decided to pursue her nursing degree.  Her nursing studies began in Texas and continued after
    moving to Denver where in 2008 she obtained her LPN certificate.

    Horizons has been fortunate to count Erika as part of our research staff since 2009. Her pleasant personality,
    easy way with people, genuine concern for our patients, and her pleasantness on the phone makes Erika perfect
    for her current role as the Recruitment Manager.  She is also bilingual in English and Spanish which enables her
    to work easily with both of our patient populations.

    When not at work Erika likes to travel, enjoy nature, and jog outside if it is warm and sunny. She also likes to cook
    with her husband and spend time with family and friends.



    Vicki Sudan, BA, CRC

    Vicki obtained her Bachelor of Arts degree at McMaster University in Hamilton, Ontario, Canada then obtained her
    Doctor of Medicine degree at Windsor University School of Medicine with course work and clinical rotations split
    between Basseterre, St. Kitts and Emory Medical Hospital in Atlanta, Georgia. After having obtained her degree
    Vicki had a change of heart and decided that her career did not lie down that particular path after all. She had had
    some experience with clinical research during her medical training and even during her prior college years and it
    had always fascinated her. Ultimately, marriage lead Vicki to Colorado and fortunately to a position as a clinical
    research coordinator at Horizons in January of 2015.

    Although Horizons is already multi-cultural and multi-national it would have become so with just the addition of Vicki
    to our staff as she brings her Indian culture and British and Canadian citizenships to our mix. Vicki’s enthusiasm
    and passion for clinical research and her truly pleasant personality makes her a joy to work with. Her naturally
    positive disposition and the authentic care she feels and shows for our study participants helps her quickly
    develop an easy rapport with patients making them feel comfortable and confident that they will receive only the
    best treatment and care while participating as a study volunteer at Horizons.

    When Vicki is not working she likes to hike, cook, vacation and make time for family and friends.
    essica is not working she enjoys leading an active lifestyle, cooking and spending time with family and friends.
