I have spent the last 13 years working in sports, building a large network in the Omaha Metro Area. This has been a perfect transition into my role with Cornerstone Staffing as the Business Development Manager. As a Business Development Manager, I will be identifying new sales leads and maintaining fruitful relationships with existing customers. I’m excited in my new role and using my network to help bridge the employer with employees. I’m originally from Frankfort, New York. I graduated from Herkimer County Community College in New York and transferred to the University of Nebraska at Omaha and graduated in 2006 with a degree in Public Relations and Advertising. I am still involved with the University of Nebraska at Omaha by going back and giving speeches to the journalism classes about careers and how to use your network to leverage relationship in the workplace. I love to volunteer, and been on several non-profit boards such as DECA, All-Star Bridges, and Chasers Charities. I’m also involved with other civic organizations around the Omaha Metro Area. For fun, I love to travel, go to the College World Series, attend concerts and relax around the pool.

For just about the last 4 years, I have been working in the Staffing Industry. Transitioning to Cornerstone has been great as I have continued to assist the great professionals and clients in the Omaha area. Prior to the staffing industry, I started my professional career in the Casino business for almost 8 years and learned everything from reporting, management, and the ins and outs of successful hiring practices. I graduated from the University of South Dakota in 2011 with my degree in Psychology. I have been happily married for the last 10 years and have two amazing daughters (and two Great Danes). In my free time I like to spend as much time outside as possible; kayaking, fishing, hunting, and anything else that includes my family.

I moved to Omaha from California in 2021 and have absolutely loved every moment of living here. I started working with Cornerstone Staffing as a personal candidate for one of the recruiters and fell in love with this company. They took such great care of me, trying to find the absolute best fit for me, great communication and very personable. After only working with them for a few weeks, they shared an interest in me joining their team, and I could not ask for a better team to work with. This office is filled with hard working and dedicated team members and never fail to make me smile! For fun I love cooking, spending time in any body of water and spoiling my dogs!
