Dave Haschig - Founder, Realtor

Inspired in his childhood by his father’s local real estate business, Dave always enjoyed seeing the joy that helping a family move could bring. He was exposed early on to the attention to detail that was required to get through a successful transaction and learned how to troubleshoot from the very beginning. He began referring his own friends to his Dad, until becoming a REALTOR himself in 2000! Since then, Dave has worked towards continuing that family real estate business, which now includes the Knox Haschig Real Estate Group – one of the leading and highest producing real estate teams in the area. And with over 100 years of combined real estate sales experience, the team has helped 1,000+ clients and sold over $500 million across Massachusetts. Dave is constantly striving to offer his clients exceptional service and well rounded knowledge and has also obtained his Real Estate Broker license, became a Notary Public, worked with local Assessor offices, and has been awarded various professional designations including the CBR(Certified Buyer Representative), the CRS(Certified Residential Specialist), MRP(Military Relocation Professional), GREEN, and e-PRO.

Tammy Haschig, Realtor

Having shared a home office with my real estate/appraiser husband for 7 years I was exposed to his work on a daily basis. It didn’t take long for me to gain an appreciation for the wonderful relationships he developed through his “work” in assisting countless people buy, sell, and appraise their homes. He loves what he does and given my experience and work history I knew it was a perfect fit for me as well. My 14 year career as an agent for a lecture bureau perfectly prepared me for a transition to real estate. As an agent/salesperson for a leading international lecture agency I had to negotiate contracts, balancing the needs of the "buying" client and our speakers who we represent. Successfully contracting a speaker for an event meant that both parties had to agree to and be happy with the contract terms. Great practice for real estate! Beyond contract negotiations it was also an agent's responsibility to work with marketing to educate them on how best to promote our speakers to our client base. And finally, working with a wide range of clients and speakers from corporations and colleges to world leaders, heads of state, celebrities, media personalities, authors, etc I honed my relational and communication skills to work effectively with each person regardless of age, cultural background, professional status, etc. I am eager to apply these skills to assist home buyers/sellers and am grateful to be on a team of experienced Realtors and appraisers. The Knox Haschig Real Estate Group brings added value to our clients in that we are uniquely qualified to assess the value of homes as we have licensed appraisers on staff. We also can offer guidance on staging your home, assist with financing options, as well as insurance needs via our brokerage firm William Raveis Real Estate (the #1 family owned real estate company in the Northeast and the #2 in Massachusetts for total sales volume). Since beginning my career in Real Estate I have earned the REALTOR designation as well as ASP (Accredited Staging Professional), and am a member of NCMAR (North Central Massachusetts Association of Realtors). I have enjoyed assisting buyers and sellers and look forward to helping you! My geographic focus is Central Massachusetts including Harvard, Devens, Leominster and surrounding cities and towns. I have spent my life living and working in these communities and am proud to call them my “homes”! When I am not assisting clients I can be found playing with my young children, husband, dog and cat, attending various family functions, volunteering at Hildreth Elementary or at our church, Grace Chapel in Lexington.

I would be honored to help you with your real estate needs.
